feat(templates): upload image for template headers; fix image-URL submit (#230)
Creating a template with an image header failed because the code sent
`example.header_url` — Meta only accepts a Resumable-Upload media handle
(`example.header_handle`) at creation time, never a plain URL.

- Resumable Upload: new `uploadResumableMedia` (meta-api) implements the
  two-step `/{app_id}/uploads` flow → media handle. Needs META_APP_ID.
- Handle derivation: `ensureImageHeaderHandle` fetches the header image
  (uploaded file OR pasted URL) and turns it into a handle before submit.
  Wired into both the submit and edit (PATCH) routes with actionable 400s
  (missing META_APP_ID, unreachable URL, wrong type, >5 MB). This fixes
  BOTH the new upload path and the previously-broken manual-URL path.
- Template builder: add an image file upload (account-scoped chat-media
  bucket via uploadAccountMedia) with preview + JPEG/PNG + 5 MB validation,
  alongside the URL field.
- Send-time fix: an approved image template now sends the public
  header_media_url as `link`; the resumable header_handle is NO LONGER
  used as a send media id (it's invalid for sends and would fail).
- META_APP_ID documented as required for image-header templates.

Scope: image headers (the issue). Helper is generic for video/document.
typecheck/lint/build green; 421 tests (10 new).

# RECOMMENDED — safe defaults exist but you'll want to set these.
# ============================================================
# Canonical public URL of this deployment (scheme + host, no trailing
# slash). Used for the sitemap and OG images. Routes that need a
# self-referential URL (invite links from /api/account/invitations,
# any future email-bound link) derive the origin from the request
# itself, so this variable is *only* needed when the request-derived
# origin would be wrong — e.g. when generating links from a cron job
# or a background worker that has no incoming request.
NEXT_PUBLIC_SITE_URL=https://crm.example.com
# ============================================================
# OPTIONAL — only needed if you use the feature.
# ============================================================
# Defense-in-depth allow-list for the hostnames that
# /api/account/invitations is willing to publish in invite URLs.
# Comma-separated, no scheme, no port (just hostnames).
#
# Why this exists: when NEXT_PUBLIC_SITE_URL is unset, invite URLs
# are derived from the incoming request's `Host` / `X-Forwarded-
# Host` header. On a typical proxied deploy the proxy sets these
# to your canonical hostname and they're trustworthy. On a *bare*
# deployment exposed to the public internet, an attacker could
# POST to the API directly with a spoofed `Host: phishing.example`
# and receive an invite URL pointing at their site.
#
# When this var is set, hostnames not on the list are rejected
# (the request falls through to the wacrm.tech fallback with a
# console.warn). When unset, behavior is unchanged from earlier
# versions — the request-derived host is trusted.
#
# Most operators don't need this: setting NEXT_PUBLIC_SITE_URL to
# your canonical URL already pins invite links there. This is for
# operators who want belt-and-braces or run multi-tenant setups
# where one app instance serves several hostnames.

# ALLOWED_INVITE_HOSTS=crm.example.com,crm-staging.example.com

# Meta App ID (Meta for Developers → App Settings → Basic). Required to
# create/edit message templates with an IMAGE header: Meta only accepts a

# returns a clear error; text/body-only templates are unaffected. Pair
# with META_APP_SECRET.
# META_APP_ID=your-meta-app-id
