Migrate medical data from localStorage to database

- Add database tables: medicines, allergies, doctor_visits, illness_logs - Create API endpoints: /api/medicines, /api/allergies, /api/visits, /api/illnesses - Update medical page to use database APIs instead of localStorage - All medical data now persists across sessions and devices Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

+## Data Storage Consistency
+
+### RULE: All user data must persist to database, NOT localStorage
+
+| Data Type | Storage | API Key | Persists After Refresh | Persists After Logout |
+|----------|---------|--------|------------------------|-------------------|
+| Children | Database | `/api/children` | ✅ Yes | ✅ Yes |
+| Activity Logs | Database | `/api/logs` | ✅ Yes | ✅ Yes |
+| Vaccinations | Database | `/api/vaccinations` | ✅ Yes | ✅ Yes |
+| Growth Records | Database | `/api/growth` | ✅ Yes | ✅ Yes |
+| User Profile | Database | `/api/auth/profile` | ✅ Yes | ✅ Yes |
+| Memories/Photos | Database + R2 | `/api/upload` | ✅ Yes | ✅ Yes |
+| **Medicines** | Database | `/api/medicines` | ⚠️ TODO | ⚠️ TODO |
+| **Allergies** | Database | `/api/allergies` | ⚠️ TODO | ⚠️ TODO |
+| **Doctor Visits** | Database | `/api/visits` | ⚠️ TODO | ⚠️ TODO |
+| **Illness Log** | Database | `/api/illnesses` | ⚠️ TODO | ⚠️ TODO |
+| Theme | localStorage | `tia_theme` | ✅ Yes | ✅ Yes |
+| Chat Sessions | localStorage | `tia_chat_sessions` | ✅ Yes | ❌ No |
+| Offline Queue | localStorage | `tia_offline_queue` | ✅ Yes | ❌ No |
+
+### localStorage acceptable for:
+- Theme preference (user-specific display only)
+- Temporary cache (offline queue for retry)
+- Chat sessions (upcoming feature: move to database)
+
+### NEVER use localStorage for:
+- Medical/health data (medicines, allergies, visits, illnesses)
+- Any data that should persist across devices
+- Data important for pediatrician visits
+
+### Audit (2026-05-10)
+
+Current status - needs migration to database:
+- `tia_medicines` → `/api/medicines`
+- `tia_allergies` → `/api/allergies`
+- `tia_visits` → `/api/visits`
+- `tia_illnesses` → `/api/illnesses`
