Mannu 678cf65d70 feat: DB-backed notification system with vaccine + activity nudges
Migration (0009): notifications table with unique daily/weekly slots,
is_read column, metadata JSONB for vaccine info. No more localStorage
for read state — syncs across devices.

API GET /api/notifications?childId=:
- Generates vaccine notifications (upsert, filtered by given vaccines at query time)
- log_nudge: if no feed/diaper/sleep logged today after noon IST
- memory_nudge: if no photo added to memories today
- garment_nudge: if wardrobe < 10 items (once per week slot)
- Returns unread first, then recent read, limit 60

API PATCH /api/notifications  — mark all read for family+child
API PATCH /api/notifications/[id] — mark single notification read

Page /notifications:
- Fetches from real API (no hardcoded mock data)
- Optimistic mark-read on tap, navigates to actionUrl
- Colored cards per type (red=vaccine, amber=log, purple=memory, pink=garment)
- Unread badge + Mark all read button in sticky header
- Legend row at bottom
