Phase 3 of the production launch plan: task reliability improvements
to prevent DB lock issues at scale and handle transient wallet API
failures gracefully.
- 3.1 Batched point expiration: rewrite per-card Python loop to chunked
processing (LIMIT 500 FOR UPDATE SKIP LOCKED). Each chunk commits
independently, releasing row locks before processing the next batch.
Notifications sent after commit (outside lock window). Warning emails
also chunked with same pattern.
- 3.2 Wallet sync exponential backoff: replace time.sleep(2) single
retry with 4 attempts using [1s, 4s, 16s] backoff delays. Per-card
try/except ensures one failing card doesn't block the batch.
Failed card IDs logged for observability.
342 tests pass.

Add async email notifications for 5 loyalty lifecycle events, using
the existing messaging module infrastructure (EmailService, EmailLog,
store template overrides).
- New seed script: scripts/seed/seed_email_templates_loyalty.py
Seeds 5 templates × 4 locales (en/fr/de/lb) = 20 rows. Idempotent.
Renamed existing script to seed_email_templates_core.py.
- Celery task: loyalty.send_notification_email — async dispatch with
3 retries and 60s backoff. Opens own DB session.
- Notification service: LoyaltyNotificationService with 5 methods
that resolve customer/card/program into template variables and
enqueue via Celery (never blocks request handlers).
- Enrollment: sends loyalty_enrollment + loyalty_welcome_bonus (if
bonus > 0) after card creation commit.
- Stamps: sends loyalty_reward_ready when stamp target reached.
- Expiration task: sends loyalty_points_expiring 14 days before expiry
(tracked via new last_expiration_warning_at column to prevent dupes),
and loyalty_points_expired after points are zeroed.
- Migration loyalty_005: adds last_expiration_warning_at to cards.
- 8 new unit tests for notification service dispatch.
- Fix: rate limiter autouse fixture in integration tests to prevent
state bleed between tests.
Templates: loyalty_enrollment, loyalty_welcome_bonus,
loyalty_points_expiring, loyalty_points_expired, loyalty_reward_ready.
All support store-level overrides via the existing email template UI.
Birthday + re-engagement emails deferred to future marketing module
(cross-platform: OMS, loyalty, hosting).
342 tests pass.

Refactor 10 db.add() loops to db.add_all() in services (menu, admin,
