feat(inbox): staged upload ack, HEIC/HEIF validation, WhatsApp silence fixes (#1605)

* fix(whatsapp): app-side unmute, close silent intake paths, health visibility

- add POST /link/unmute and a Reactivate control on the Pausad state
- company resolution: transient query errors release the row for sweep
  retry; genuine zero-options sends M19 instead of parking silently
- media from unlinked senders bypasses the hourly greeting throttle
  (10 min burst window, daily cap kept)
- GET /link returns 7-day failed-delivery and parked-inbound counts;
  sweep summary logs outboundFailed24h

* fix(documents): real HEIC/HEIF magic-byte validation, bilingual upload errors

- detect ISO-BMFF ftyp brands (heic/heix/heim/heis/hevc/hevx/hevm/hevs,
  mif1/msf1) instead of exempting image/heic from validation; declared
  heic/heif accepts either family member (iOS labels vary)
- new INBOX_UPLOAD_* structured error codes replace raw English strings
  on the inbox upload and attach-document routes
- registry doc corrected to the real 10 MB cap

* feat(inbox): staged upload with instant ack and deferred AI extraction

- web uploads insert the inbox item as status processing and respond
  immediately; Bedrock extraction and supplier match run via after()
  with a CAS flip to received (email and WhatsApp channels keep the
  synchronous path)
- widen invoice_inbox_items.status CHECK to include processing
  (migration 20260813180000, pg-real test included)
- crash-recovery sweep cron (*/2) flips stale processing rows;
  bulk-book skips extraction_in_progress items
- workspace: processing chip, in-flight rows disable actions, realtime
  flip, retry-extraction button for empty extractions
- picker accept list drops HEIC/HEIF so iOS transcodes library photos
  to JPEG; server allowlists unchanged (supersedes 2026-08-01 HEIC
  decision, see DECISIONS.md)

* fix(migrations): bump inbox processing-status migration past main's latest

Main merged 20260813210000 while this PR was in flight; an inserted
version older than the latest applied aborts the prod db push at merge.
Renamed 20260813180000 to 20260813213000 and updated references.
