Paul Nothaft 78c8e9d9f9 feat(whatsapp): WhatsApp Business API notification channel (#640 part D)
Ports filpgame/picpeak's WhatsApp integration with substantial adaptation
to fit our codebase patterns. Deliver the gallery-ready notification via
Meta Graph API in addition to (or instead of) email — useful where the
customer base expects WhatsApp by default. Strictly opt-in behind the new
`whatsapp` feature flag.

### Backend

- **Migration 136** (`whatsapp_configs` + `whatsapp_queue`). Loose-FK on
  `event_id` matching our `inbound_documents` / `expenses` pattern (NOT
  filpgame's hard FK — deleting an event shouldn't RESTRICT on stale queue
  rows). Composite index on `(status, retry_count, created_at)` covers the
  poll path.
- **`whatsappService.js`**: thin Meta Graph client. Meta API version bumped
  v19 → v20 (filpgame's v19 deprecates Q3 2026); configurable via
  `WHATSAPP_META_API_VERSION` env var. Timeout dropped 10s → 8s for
  processor budget. Errors surface the Meta `error.code` so the processor
  can tell retryable from permanent.
- **`whatsappProcessor.js`**: queue processor polling every 30s (configurable
  via `WHATSAPP_QUEUE_POLL_MS`), 10 messages per cycle, 3 retries before
  marking `failed`. Default language sourced from
  `app_settings.general_default_language` (matches our email-language
  resolution pattern); replaces filpgame's hardcoded `pt_BR` fallback.
  Falls back to `en_US` if nothing is configured. No-ops gracefully when
  the `whatsapp` flag is off, the config row is missing, or the access
  token isn't set.
- **`adminWhatsapp.js`**: three routes (GET/PUT config, POST test). Gated
  by `requireFeatureFlag('whatsapp')` so operators who haven't enabled it
  can't see the surface. Access token masked as `'********'` on GET;
  masked values silently preserve the stored token on PUT. Enabling with
  no Phone Number ID, template name, or token (and none stored) fails at
  the validator.
- **Two hook points** in `adminEvents.js`:
  - **Create-and-publish-in-one-step**: queues immediately after the
    `gallery_created` email when `!isDraft && customerPhone &&
    waConfig.enabled`. Password from `req.body` is still in scope.
  - **Publish-from-draft** (`POST /:id/publish`): queues with the password
    the admin re-typed via PR #627's `PublishGalleryDialog`. When no
    password was typed (legacy API consumers without dialog), passes empty
    string so the password line renders blank rather than leaking the
    `(set at creation)` sentinel.
- **`server.js`**: starts `whatsappQueueProcessor` at boot. Non-fatal if it
  fails to start (logged as warning).
- **`feature_flags`**: new `whatsapp` flag in `KNOWN_FLAGS` and
  `DEFAULT_FLAGS` (default false).

### Frontend

- **`featureFlags.service.ts`**: `'whatsapp'` added to `FeatureKey` union.
- **`FeaturesTab.tsx`**: WhatsApp card in the Communication section
  (between Incoming mail and Messaging). Smartphone icon, "new" status,
  sidebar-hidden (no sidebar entry — config lives under Settings).
- **`whatsapp.service.ts`** (new): typed client for the three admin routes.
- **`WhatsAppTab.tsx`** (new): Settings tab. Form for Phone Number ID,
  WABA ID, access token (masked toggle), template name, and enabled flag.
  Separate card below for a static test send. Token masking matches the
  server's `'********'` sentinel — admin can edit other fields without
  re-entering the token.
- **`SettingsPage.tsx`**: WhatsApp tab nav item gated on `flags.whatsapp`
  (so it shows only when the feature is enabled); render block wires
  `<WhatsAppTab />`.

### i18n

22 new EN + 22 new DE entries covering the Settings tab form, the
Features-tab card, plus `admin.activities.whatsapp_config_updated` +
`admin.notificationMessages.whatsappConfigUpdated` for the bell /
dashboard surfaces from PR #637.

### Deliberately NOT included

- filpgame's **password-encryption-at-rest** layer
  (`password_encrypted`/`password_iv`/`password_key_version` columns).
  Our publish-from-draft password recovery uses the admin re-type flow
  from #627 (PublishGalleryDialog) — no plaintext at rest.

### Setup notes for operators

1. Create a Meta Business Account + WhatsApp Business App.
2. Register a phone number and obtain `phone_number_id` + `waba_id`.
3. Create a system-user access token (long-lived recommended).
4. Submit a message template for approval. The default `gallery_ready`
   expects 5 body parameters: customer name, event name, gallery link,
   password line, expiry date.
5. Enable the `whatsapp` feature flag.
6. Enter credentials under Settings → WhatsApp, send a test, then enable
   delivery.

### Test plan

- [x] Backend `node -c` on all new/changed files clean
- [x] `tsc --noEmit` on frontend clean
- [x] Backend dev container restart picks up new files, /health OK
- [ ] Manual: enable `whatsapp` flag → Settings → WhatsApp tab appears
- [ ] Manual: save config with masked-only token (existing token preserved)
- [ ] Manual: enable=true without phone_number_id rejected at PUT
- [ ] Manual: enable=true without stored or new token rejected at PUT
- [ ] Manual: create-and-publish event with customer_phone → queue row
      inserts with message_type='gallery_created'
- [ ] Manual: publish-from-draft via PublishGalleryDialog with password →
      queue row uses the admin-typed password in the {{4}} line
- [ ] Manual: test send to a real phone with valid Meta config + approved
      template → Meta returns messages[0].id, toast shows the id
- [ ] Manual: bell renders "WhatsApp configuration updated" in DE when
      the config_updated activity fires (via PR #637 smart default)

Database Migrations

This directory contains database migrations for the PicPeak photo sharing platform.

Directory Structure

/core

Essential migrations that are always run for new deployments. These include:

  • init.js - Initial database schema creation
  • Backup service tables (029-035)
  • Gallery feedback tables (033)
  • Pre-generated watermarks (061)

/legacy

Migrations needed only when upgrading from older versions. New deployments can skip these as the core schema already includes all necessary tables and columns.

For New Deployments

If you're deploying this application for the first time:

  1. The initializeDatabase() function in src/database/db.js will create all necessary tables
  2. Only migrations in the /core directory will be run
  3. This ensures a clean, optimized database schema

For Existing Deployments

If you're upgrading from an older version:

  1. All migrations (both core and legacy) will be run in sequence
  2. The migration system tracks which migrations have been applied
  3. Only new migrations will be executed

Running Migrations

# Development
npm run migrate

# Production
npm run migrate:prod

Note on Duplicate Migration Numbers

The legacy directory contains renamed duplicates:

  • 014_add_host_name_to_events_duplicate.js (was duplicate of 014)
  • 027_add_rate_limit_settings_duplicate.js (was duplicate of 027)

These have been renamed to avoid conflicts while preserving the migration history.
