78b42dfba9 feat: WhatsApp interactive messages (reply buttons + lists)
Add full support for WhatsApp Cloud API interactive messages across the
inbox, automations, and a new quick-replies feature. Extends the
interactive plumbing that previously existed only for the Flows engine.

Sending
- send-message core handles `interactive` (reply buttons ≤3, list ≤10
  rows) via the existing Meta senders; validated server-side before send.
- Inbox composer gains a "+" menu → builder dialog with live WhatsApp-style
  preview + Meta char limits (button 20, list row 24, body 1024).
- Automation "Send Buttons" / "Send List" steps in the builder.
- Public v1 /messages accepts type=interactive.

Storage / round-trip
- migration 035: messages.interactive_payload JSONB + quick_replies table.
- Outbound interactive persists the structured payload (composer,
  automations, and Flows) so the thread re-renders the buttons/rows.

Receiving
- Bubble renders outbound interactive via the shared preview; inbound taps
  (button_reply/list_reply) keep the "chosen option" affordance.

Automations
- New `interactive_reply` trigger matches on tapped button/list IDs
  (exact), enabling chained multi-step menus.

Quick replies
- New account-scoped quick_replies (text or interactive snippets), managed
  in Settings and insertable from the composer; "Save as quick reply" in
  the builder.

Shared core in src/lib/whatsapp/interactive.ts + src/components/interactive/.
Includes unit tests for the validator, send-param validation, the
interactive_reply trigger match, and the new automation step/trigger
validation. typecheck + lint clean; full suite green.

b0194dfc27 feat(ai): polish auto-reply — inbox controls, real handoff, usage logging
Makes the AI auto-reply bot visible and controllable from the inbox,
completes the handoff, and records token spend. Builds on the existing
lib/ai engine rather than replacing it.

Track A — user-facing
- messages.ai_generated flag → small "AI" badge on bot-generated bubbles
- "Take over" / "Resume AI" banner per conversation
  (POST /api/ai/autoreply/[id]) — take-over pauses + assigns to the agent
- handoff now assigns to a configurable target (agent or unassigned
  queue) and writes an internal note summarizing the exchange; the
  existing on_conversation_assigned trigger notifies the assignee
- Settings → AI: "Hand off to" target picker

Track B — observability + safety
- providers return normalized token usage; logged per run to ai_usage_log
  (admin-readable) from both auto-reply and draft
- account-wide auto-reply rate limit (30/min) on top of the
  per-conversation cap

Migration: 033_ai_reply_polish.sql (messages.ai_generated,
ai_configs.handoff_agent_id, conversations.ai_handoff_summary,
ai_usage_log). Tests + typecheck + lint pass (607 tests).

feat(webhook,engines): account-scoped routing
PR 8 of the multi-user accounts series. Flips the WhatsApp webhook,
automations engine, and flows engine from per-user tenancy to
per-account so a shared inbox actually behaves like one.

Why this matters
- Pre-this-PR: an inbound message resolved the recipient by
  whatsapp_config.user_id and dispatched only that user's
  automations / flows. Teammates joining via an invite would see
  the message in the shared inbox but their automations / flows
  never fired.
- Also fixes incipient NOT NULL violations from migration 017.
  That migration added `account_id NOT NULL` to automation_logs,
  automation_pending_executions, flow_runs, and deals. Inserts in
  the engines hadn't been updated yet — any production run would
  500 with a column violation. This PR adds account_id to every
  such insert.

Surface
- `src/app/api/whatsapp/webhook/route.ts`
  - Resolves `config.account_id` AND `config.user_id` from the
    matched whatsapp_config row. Passes accountId through every
    downstream call. user_id is kept as `configOwnerUserId` and
    used only for NOT NULL FK audit columns on contact /
    conversation inserts.
  - `findOrCreateContact` / `findOrCreateConversation` look up by
    account_id and insert with both columns.
  - `flagBroadcastReplyIfAny` matches broadcasts by account_id so
    any teammate's broadcast is updated when a customer replies.
  - `dispatchInboundToFlows` and `runAutomationsForTrigger` now
    take `accountId` instead of `userId`.
- `src/lib/automations/engine.ts`
  - `DispatchInput.userId` → `accountId`.
  - `runAutomationsForTrigger` queries automations by account_id.
  - `executeAutomation` inserts into automation_logs with both
    account_id (tenancy) and user_id (audit, from automation row).
  - `wait` step inserts into automation_pending_executions with
    account_id.
  - `create_deal` step inserts into deals with account_id.
  - `assign_conversation` / `close_conversation` /
    `resolveConversationId` filter by account_id.
  - `resumePendingExecution` row shape now includes account_id;
    cron passes it through.
  - engineSendText / engineSendTemplate calls pass
    `accountId: args.automation.account_id`.
- `src/lib/flows/engine.ts`
  - `DispatchInboundInput.userId` is kept (audit) and
    `accountId` is added (tenancy).
  - `loadActiveRunForContact`, `isDuplicateInbound`,
    `findEntryFlow` all query by account_id.
  - `startNewRun` inserts into flow_runs with account_id.
  - All `engineSend*` calls pass `accountId: run.account_id`.
- `src/lib/automations/meta-send.ts` + `src/lib/flows/meta-send.ts`
  - All four engine senders (text, template, media, interactive
    buttons/list) accept `accountId` and look up the contact +
    whatsapp_config by account_id. user_id stays for inserts.
- `src/lib/flows/types.ts`
  - `FlowRow`, `FlowRunRow`, `DispatchInboundInput` gain
    `account_id` / `accountId`.
- `src/types/index.ts`
  - `Automation` gains `account_id`. Doc note on the user_id
    field clarifying it's audit-only post-multi-user.
- `src/app/api/automations/cron/route.ts`
  - Pass account_id from the pending row to resumePendingExecution.
- `src/app/api/automations/engine/route.ts`
  - Uses `getCurrentAccount()` from #169 to resolve the caller's
    account, then dispatches with accountId.
- `CHANGELOG.md` — Fixed entry explaining the inbox / NOT NULL fix.

Backwards compatibility
- All affected tables already have account_id from migration 017.
  This PR populates it on insert paths that hadn't been updated.
- The `user_id` columns are kept everywhere — they still identify
  the agent / author for audit display. They just no longer
  enforce tenancy.

Verification
- `npm run lint`      → 0 errors (same 19 pre-existing warnings)
- `npm run typecheck` → clean (had 4 errors mid-refactor; all
                        resolved by the call-site updates)
- `npm test`          → 366/366 pass (engine tests are pure unit
                        tests over helper functions; not affected)
- `npm run build`     → succeeds

feat(flows): canvas / mind-map view (PR 2b of 3 — full editing)
Closes the editing-affordance gap from PR 2a. The canvas is now in
full parity with the list view for everything that fits in a node
graph: connections, deletes, and adding nodes all work on-canvas.

Adds:

  - Per-slot Handle components on the custom node renderer. Single-
    outgoing types get one handle on the right edge; condition gets
    `true` / `false` handles; send_buttons and send_list render slot
    rows inside the card with one handle each, so the user can SEE
    which button or list row they're wiring. Every non-start node
    gets a target handle on the left.

  - Drag-to-connect (`onConnect`). Looks up the source node, dispatches
    the right config patch via the new `applyEdgeConnection(node,
    sourceHandle, target)` helper, and routes through updateNodeConfig.
    Rejects self-loops silently (a button whose target is its own node
    = infinite reprompt).

  - Keyboard delete on nodes (Backspace + Delete, both for cross-OS
    parity). Routes through removeNode, which now ALSO unlinks every
    inbound reference via the new `unlinkNodeReferences(nodes, key)`
    helper. No more dangling arrows after a delete — the validator
    previously flagged these as errors and the user had to chase them
    down manually.

  - Edge delete. Selecting an edge + Delete clears just that slot's
    next_node_key (rather than removing anything), via the same
    applyEdgeConnection helper passing "" as the target.

  - Floating "+ Add node" button (React-Flow Panel, bottom-right).
    Same dropdown as the list view; drops the new node at the visible
    viewport center via reactFlow.screenToFlowPosition.

New pure helpers in src/lib/flows/edges.ts (no React, fully unit-
tested — 18 new tests, 319 total passing):

  - outgoingSlots(node) — list of {id, label} per outgoing slot.
  - applyEdgeConnection(node, sourceHandle, targetKey) — config patch
    for a drag-to-connect, or null for unrecognised handles.
  - unlinkNodeReferences(nodes, deletedKey) — clears every direct +
    nested reference to deletedKey. Returns nodes-by-identity when
    no reference matches to avoid needless re-renders.

The hook's removeNode is the only consumer of unlinkNodeReferences
right now, which means LIST-view deletes also stop leaving dangling
refs — strict improvement for both views.

feat(flows): canvas / mind-map view (PR 1 of 3 — read-only)
The second half of the user feedback that drove send_media: the
linear-list editor reads as a checklist, not a branching flow, which
made conversational structures hard to understand at a glance. This
introduces a canvas view alongside the list — boxes + arrows, drag-
zoom-pan, labeled edges per branch slot. Canvas is the new default;
the list stays as a fallback toggle (per-browser preference,
persisted to localStorage).

PR 1 scope is intentionally read-only: render, don't edit. The
foundation is testable in isolation before adding drag-to-persist,
side-panel editing, and drag-to-connect (PR 2) and polish like
keyboard shortcuts, mobile fallback, and validator integration
(PR 3).

Pieces:
  - New @xyflow/react (~30 KB gz) + @dagrejs/dagre (auto-layout for
    pre-existing flows whose position_x / position_y are all zero —
    flow_nodes already reserved those columns in migration 010
    precisely for this).
  - Shared module src/components/flows/shared.tsx lifts NodeType,
    BuilderNode, NODE_META, summarizeNode, truncate so both views
    render nodes identically.
  - Pure helpers (no React, fully unit-tested):
      src/lib/flows/edges.ts   — derive labeled canvas edges per
                                 outgoing slot (button, list row,
                                 condition branch)
      src/lib/flows/layout.ts  — dagre wrapper + shouldAutoLayout
                                 guard so manually-positioned flows
                                 never get rearranged on open
  - FlowCanvas — client component, custom node renderer matching the
    list view's collapsed-card styling, MiniMap + Controls, attribution
    hidden.
  - FlowEditorShell — owns the Canvas / List toggle, conditionally
    mounts the right view.

21 new unit tests (layout + edges); existing 271 still pass.

feat(flows): add send_media node for image / video / document sends
Lets flows attach an image, video, or document (e.g. PDF invoice /
receipt) to a customer message — the most-requested gap in v1 was that
nodes were text-only. Single node with a `media_type` discriminator
rather than three node types: Meta's wire payload differs only in the
top-level key, so three types would triple the surface area (forms,
engine cases, menu entries) for no behavioural difference.

Files are uploaded directly from the builder to a new public
`flow-media` Supabase Storage bucket (per-user RLS, 16 MB cap, MIME
allowlist) and the resulting public URL is what Meta fetches at send
time. Same trade-off as the existing avatars bucket.

feat(flows): soft-GA — open to all users + Beta label
The Flows feature was previously gated on a per-account
`profiles.beta_features` opt-in: the sidebar entry was invisible
to non-beta accounts, every /api/flows route 404'd, the webhook
dispatcher was a no-op, and the agent-handoff pause was skipped.

This PR opens the surface to every authenticated user. A small
"Beta" chip in the sidebar nav + on the /flows page H1 keeps the
"young feature" signal without holding anyone out.

Removed:
- `src/lib/flows/feature-flag.ts` + its tests (-11 tests).
- The `requireFlowsBeta` / `requireFlowsBetaAndOwnership` helpers
  in the API routes — collapsed to plain `requireUser` / RLS
  ownership.
- The `isProfileFlowsEnabled` helper + branch in the webhook
  dispatcher — the runner takes the cheap "no_match" exit on
  accounts with no active flows (single indexed SELECT).
- The agent-handoff pause gate in /api/whatsapp/send — the UPDATE
  matches zero rows when no active run exists, also cheap.
- Client-side beta gates in the 3 flows pages (and the redundant
  `useAuth` + `profileLoading` plumbing they needed).
- The defensive message-bubble gate that would have rendered
  interactive replies as plain text for non-beta accounts.
- The `betaKey` field on the sidebar NavItem schema, replaced by a
  simpler boolean `beta` that purely drives the visual chip.

Kept:
- `profiles.beta_features` column. Generic mechanism for future
  beta gates; no current feature reads it. Comments in
  `src/types/index.ts` + `use-auth.tsx` updated to say so.
- The chip can be removed in a one-liner once the team's satisfied
  Flows has bedded in.

perf(flows): drop wasted re-read after reprompt reset + defensive limit(1)
Two small things noticed in review:

1. handleReplyForActiveRun did UPDATE reprompt_count=0 → SELECT *
   the whole row → use it. The re-read existed because the
   collect_input capture branch wrote `vars` to the DB without
   mirroring the change to the local `run` object — so the next
   advance step would interpolate stale vars otherwise.

   Mirror the UPDATE in-memory instead. Also skip the reset UPDATE
   when reprompt_count is already 0 (the common case after a
   successful collect_input — that branch already zeroed it).

2. loadActiveRunForContact used .maybeSingle() which throws on >1
   row. The partial unique index makes that impossible by design,
   but a migration glitch or manual SQL could produce one and would
   crash dispatch for that contact's webhook forever. Switch to
   .order().limit(1) so the runner picks the newest and lets the
   cron sweep clean up duplicates if any ever appear.

perf(flows): preload all flow_nodes once per dispatch
The advance loop called loadNode() on every iteration — one DB
round trip per node visited. A flow with 5 chained auto-advance
nodes (send_message → condition → set_tag → send_message → end)
cost 5 sequential round trips synchronous in the webhook hot path.
At ~50ms each that's 250ms before the customer sees anything.

Switch to a single upfront SELECT into a Map<node_key, FlowNodeRow>
keyed on the flow_id, passed through advanceFromNodeKey and
handleReplyForActiveRun. The advance loop is now in-memory and the
hot path costs one round trip regardless of chain length.

node_not_found semantics are preserved: missing keys still end the
run with that reason, same as the old per-node lookup.

fix(flows): atomic execution_count increment via SECURITY DEFINER RPC
startNewRun read flows.execution_count from a cached row and wrote
`cached + 1`. Two concurrent webhooks starting runs on the same flow
for different contacts both read N and both write N+1 — one count
permanently lost.

Mirrors the automations engine's solution (migration 007): a tiny
SECURITY DEFINER function that does the increment server-side, locked
to the service role. The engine's call becomes a single RPC.

The counter is best-effort: if the RPC fails we log + continue rather
than failing the run for a stat error.

fix(flows): redact customer text from reply_received event payload
The `reply_received` event was persisting `text: message.text` verbatim
into flow_run_events.payload. A customer prompted "what's your card
number?" by a collect_input node would leave the PAN sitting in the
events table forever, surfaced via the runs viewer to anyone with
access.

Switch to `text_length` only. The `node_entered` event already records
`captured_length` for the same reason after a successful capture; this
makes the asymmetry symmetric.

feat(flows): templates + v1.5 nodes (collect_input/condition/set_tag) + run-history viewer (PR 4/4)
Final feature PR before GA cleanup. Closes the gap between "flow
runner works" (PR 2) and "users have everything they need to build
real automation" — three new node types, plain-text sends actually
sending, three starter templates, a run-history page for debugging.

What landed:

  1. engineSendText helper (src/lib/flows/meta-send.ts) — wraps
     sendTextMessage with the phone-variant retry + DB persistence
     pattern. Unblocks send_message + collect_input nodes that
     previously auto-advanced without sending.

  2. Three new node types in the engine:
     - collect_input: sends a prompt, suspends, captures the next
       text reply into flow_runs.vars[var_key], advances. Supports
       {{vars.X}} interpolation in downstream prompts + handoff
       notes.
     - condition: branches on subject (var / tag / contact_field)
       with operators (equals / contains / present / absent).
       Auto-advancing, no Meta call. Pure predicate logic exported
       as evaluateConditionPredicate with 7 new unit tests.
     - set_tag: upsert/delete on contact_tags then advance. Non-
       fatal on write failure — logged + advances anyway so a tag
       glitch doesn't strand the customer.

  3. Real send_message — calls engineSendText, logs the result,
     handles errors by ending the run with status='failed'. Same
     {{vars.X}} interpolation.

  4. Three starter templates (src/lib/flows/templates.ts):
     - Welcome menu (the owner's brief example)
     - FAQ bot (keyword → list → answers → end)
     - Lead capture (first_inbound → collect_input chain → handoff
       with vars in the note)
     POST /api/flows now accepts {template_slug} to clone a
     template into a fresh draft. GET /api/flows/templates exposes
     the gallery shape (no nodes payload — fetched on actual clone).

  5. Builder UI extensions:
     - NODE_META + config sub-forms for collect_input, condition,
       set_tag.
     - Template gallery on the /flows New-flow dialog (loads from
       /api/flows/templates, falls back gracefully if absent).
     - "Runs" button in the editor header → /flows/[id]/runs.

  6. Run-history viewer at /flows/[id]/runs — newest-first list of
     the 50 most recent runs, with expandable per-run event
     timeline (started, node_entered, message_sent,
     reply_received, fallback_fired, handoff, timeout, error,
     completed). Useful for debugging "why didn't my flow advance?"
     from the brief's use case.

  7. Validator updates: new error rules for each new node type
     (prompt_text required, var_key alphanumeric, operator valid,
     true_next/false_next exist, etc.). outgoingEdges helper now
     covers collect_input/condition/set_tag for reachability.

All gated behind isFlowsEnabled(profile). Non-beta accounts see no
change. Run-history API is also 404 for non-beta.

Validation: 173/173 tests pass (added 7 new for the predicate);
typecheck + lint + build all clean.

feat(flows): no-code builder UI + flows API + validator (PR 3/4)
Ships the surface that lets opted-in beta accounts build, save, and
activate WhatsApp conversation flows entirely from the web UI — no
SQL fixtures needed. Sidebar gets a "Flows" entry (hidden for
non-beta accounts), the /flows list page surfaces existing flows,
/flows/[id] is the linear-list editor.

Wraps the runner from PR 2 with everything a real user needs to
build the welcome-menu example end-to-end.

What landed:

  1. `src/lib/flows/validate.ts` — pure validator. Checks entry
     node exists, all next_node_key refs resolve, no unreachable
     nodes, Meta-limit violations (button title ≤20, ≤3 buttons,
     ≤10 list rows, ≤24 chars per list row). 24 unit tests.

  2. `src/app/api/flows/route.ts` — GET (list user's flows),
     POST (create draft).

  3. `src/app/api/flows/[id]/route.ts` — GET (load with nodes),
     PUT (replace name + trigger + nodes; delete-then-insert),
     DELETE (cascade clean-up).

  4. `src/app/api/flows/[id]/activate/route.ts` — status toggle.
     Activation runs the validator; returns 422 + the full issue
     list when blocked.

  5. `src/app/(dashboard)/flows/page.tsx` — list of cards, "New
     flow" dialog, delete with confirm.

  6. `src/app/(dashboard)/flows/[id]/page.tsx` — editor shell
     that loads data and hands it to FlowBuilder.

  7. `src/components/flows/flow-builder.tsx` — the editor itself.
     Header with name + save/activate/pause/delete; trigger
     panel; entry-node picker; node list with expandable per-node
     config forms (start, send_buttons, send_list, send_message,
     handoff, end); bottom validation panel that mirrors what the
     server's activate endpoint would reject.

  8. `src/components/layout/sidebar.tsx` — Flows entry between
     Automations and Settings, rendered only when isFlowsEnabled.

Every API route + page is gated server-side by isFlowsEnabled —
non-beta accounts get 404 (not 403) so the routes don't even hint
at existing. UI gate is for snappy redirect; security is at the
API layer.

Validation: 166/166 tests pass (added 24 validator tests);
typecheck + lint + build all clean.

feat(flows): runner engine + webhook integration + agent-handoff + cron sweep (PR 2/4)
Brings the Flows feature alive end-to-end for beta-opted-in accounts.
Still no UI — flows are defined via direct SQL inserts in v1; the
no-code builder lands in PR 3. Everything in this PR is gated behind
`isFlowsEnabled(profile)` so non-beta accounts behave identically to
before.

What landed:

  1. `src/lib/flows/types.ts` — DB row + discriminated-union node
     config types, plus the `ParsedInbound` shape and a
     `DEFAULT_FALLBACK_POLICY`.

  2. `src/lib/flows/fallback.ts` — pure policy resolver. Decides
     whether an unknown reply triggers a reprompt (up to N times),
     a handoff, or end. 11 unit tests.

  3. `src/lib/flows/engine.ts` — `dispatchInboundToFlows()` entry
     point. Loads the active run (if any), checks idempotency via
     `flow_run_events`, advances the run through a synchronous
     auto-advance loop that suspends only at nodes that need
     customer input. Each suspending node calls
     `engineSendInteractive{Buttons,List}` and persists the new
     current_node_key via an optimistic UPDATE with a precondition
     on the OLD key — concurrent inbounds collide cleanly.
     11 unit tests for the pure-logic helpers.

  4. `src/app/api/whatsapp/webhook/route.ts` — invokes the runner
     between the broadcast-reply flag and the automation dispatch.
     When the runner consumes the inbound (started a flow, advanced
     one, applied a fallback), suppresses `new_message_received`
     and `keyword_match` automation triggers — the customer is
     navigating the bot menu, not throwing a keyword. Relationship
     triggers (new_contact_created, first_inbound_message) still
     fire regardless.

  5. `src/app/api/whatsapp/send/route.ts` — after a successful
     agent message, marks any active flow run for that contact as
     `paused_by_agent`. Best-effort: a write failure is logged but
     doesn't block the send response.

  6. `src/app/api/flows/cron/route.ts` — sweeps active runs whose
     `last_advanced_at` is older than the flow's
     `fallback_policy.on_timeout_hours` (default 24h). Marks them
     `timed_out` and writes a `flow_run_events.timeout` row. Re-uses
     `AUTOMATION_CRON_SECRET` so operators don't have to provision
     a second secret.

Test surface in this PR:
  - 142/142 tests pass (added 22 new unit tests across fallback +
    engine pure logic)
  - typecheck clean
  - 0 new lint errors
  - build clean

Manual end-to-end verification arrives via the SQL fixture in the
PR description (a 3-node Welcome → buttons → handoff flow).

feat(flows): foundation for interactive WhatsApp messages (PR 1/4)
Foundation for the upcoming WhatsApp chatbot flow builder. No runner,
no UI yet — just the plumbing that lets the codebase SEND interactive
messages (button replies + lists) and RECEIVE the taps as structured
message rows. Plan: ~/.claude/plans/understood-research-such-functionality-binary-lake.md

## What's in this PR

### Migration 010_flows.sql
- New tables: flows, flow_nodes, flow_runs, flow_run_events
- Linchpin partial unique index on flow_runs(user_id, contact_id) WHERE status='active' — at most one active run per contact, makes concurrent webhook deliveries idempotent at the DB layer
- Widens messages.content_type CHECK to allow 'interactive'
- New messages.interactive_reply_id column for the tapped button/row id
- RLS on every table; flow_runs added to supabase_realtime publication
- Idempotent throughout — matches the 009_message_actions.sql template

### Interactive Meta senders (src/lib/whatsapp/meta-api.ts)
- sendInteractiveButtons: type='interactive', interactive.type='button', up to 3 reply buttons
- sendInteractiveList: type='interactive', interactive.type='list', up to 10 rows across sections
- Limits exported as INTERACTIVE_LIMITS so flow validation can share the constants
- All Meta caps validated BEFORE the network call (button title ≤20 chars, list row title ≤24 chars, ≤10 total rows, no duplicate row ids, body ≤1024 chars, etc.) — misconfigured flows fail at save time instead of as a customer-facing 400 mid-conversation

### Webhook (src/app/api/whatsapp/webhook/route.ts)
- Extends WhatsAppMessage interface with `interactive?: { type, button_reply?, list_reply? }`
- parseMessageContent returns a new `interactiveReplyId` field; refactored to use a shared `empty` base so every return site picks up the new field without 9 explicit copies
- New `case 'interactive'`: uses the tapped option's TITLE as content_text (so the inbox bubble reads "Existing customer", not a UUID) and stashes the id separately
- 'interactive' added to ALLOWED_CONTENT_TYPES so the messages insert no longer coerces it to 'text'

### Inbox bubble (src/components/inbox/message-bubble.tsx)
- New `case "interactive"` in MessageContent renders the tap with a small "↩ Button reply" affordance so agents reading the inbox can tell at a glance that this was a tap rather than the customer typing the same words

### Types (src/types/index.ts)
- ContentType union extended with 'interactive'
- Message.interactive_reply_id field

### Engine helpers (src/lib/flows/)
- admin-client.ts: thin service-role client wrapper, mirrors automations/admin-client.ts
- meta-send.ts: engineSendInteractiveButtons / engineSendInteractiveList — adapts the Meta senders for service-role use, persists messages with sender_type='bot' content_type='interactive', uses the same phone-variant retry as automations/meta-send.ts. Unused in PR #1; ready for the runner in PR #2

### Tests
- 13 new vitest cases in meta-api.test.ts covering Meta's limit validation + payload-shape assertions for both interactive senders

## Validation
- npm test → 102/102 (was 89; 13 new)
- npm run lint → 0 errors
- npm run typecheck → clean
- npm run build → clean

## What's NOT in this PR
- The runner (dispatchInboundToFlows) — PR #2
- Builder UI / API surface — PR #3
- collect_input / condition / set_tag nodes + templates — PR #4
- react-flow canvas + http_fetch — v2 (PR #5)

## Risks tracked from the plan
- messages.content_type CHECK widening: grep'd every consumer; message-bubble.tsx, reply-quote.tsx, send/route.ts, automations/meta-send.ts all handle the new variant correctly (or accept it as a defaulted fallthrough)
- engineSendText / engineSendInteractive share ~80% of code; deliberately not pre-factored yet — let both stabilize, extract a shared base in PR #2 once the shape settles

feat(beta): per-account beta_features flag on profiles, gating Flows
Scaffolding for the upcoming WhatsApp Flows feature. The whole Flows
stack (interactive button/list send + parse, server-side runner, no-
code builder, templates) will land across the next ~4 PRs *behind*
this gate so the owner can dogfood the feature on their own account
before exposing it to teammates or downstream pullers of the OSS.

What this lands:

  1. `profiles.beta_features TEXT[] NOT NULL DEFAULT ARRAY[]::TEXT[]`
     — generic opt-in column, lives on the existing profiles table.
     Empty by default for every existing row.

  2. `src/lib/flows/feature-flag.ts` — `isFlowsEnabled(profile)`
     predicate + `BETA_FEATURE_FLOWS` constant. Single source of
     truth for the gate; later PRs import this in every guarded
     surface (sidebar nav, /flows page, /api/flows routes, webhook
     dispatcher).

  3. `Profile.beta_features` added to the shared TS type and the
     auth hook's local copy. Auth hook loads the column and
     defaults it to `[]` defensively if the DB read returns null.

  4. 11 unit tests covering null/undefined/empty/mismatched cases,
     including case sensitivity (only lowercase `'flows'` opts in)
     and defensive guards against malformed input.

How the owner enables it for their own account, once merged:

    UPDATE profiles
    SET beta_features = array_append(beta_features, 'flows')
    WHERE user_id = '<their-auth-uid>';

How we ship it to everyone, when ready: grep-and-delete the
`isFlowsEnabled()` callsites in one cleanup PR.
