fix(broadcasts): per-recipient variables, webhook status sync, rate limit
Three correctness bugs were making the existing broadcast flow wrong,
not just incomplete.

1. Per-recipient variables were broken
   use-broadcast-sending.ts computed templateParams per contact but shipped
   only templateParams[0] to the API, so every contact in a batch received
   contact 0's personalization (name/email/etc).

   Fix: extend POST /api/whatsapp/broadcast to accept a per-recipient
   shape `{ recipients: [{ phone, params }], ... }`. Legacy
   `{ phone_numbers, template_params }` still accepted. Hook sends per-
   recipient payloads; API returns whatsapp_message_id per phone.

2. Webhook never updated broadcast_recipients
   handleStatusUpdate in webhook/route.ts only mirrored Meta status onto
   the `messages` table. broadcast_recipients had no correlation column,
   so delivered_count / read_count / replied_count never advanced for
   real broadcasts.

   Fix (migration 003):
     - broadcast_recipients.whatsapp_message_id (+ UNIQUE index) for
       Meta-message-id correlation
     - composite index (broadcast_id, status) for fast aggregate scans
     - AFTER INSERT/UPDATE/DELETE trigger that recomputes parent
       broadcasts counts via COUNT(*) FILTER — sender + webhook only
       touch the recipient row, aggregates stay consistent

   Webhook:
     - handleStatusUpdate also updates broadcast_recipients with forward-
       only status guard (read cannot regress to sent on a replay)
     - processMessage flags the replied recipient row when an inbound
       message arrives from a recent broadcast contact

3. Rate limiting did not match spec
   Batch 50 / no delay → Batch 10 / 1s between batches, matching the spec
   and Meta's per-phone-number rate ceiling.

Also: extract statusConfig from both page components into
src/lib/broadcast-status.ts (single source of truth for PR B). Add
whatsapp_message_id to BroadcastRecipient type.
