This commit implements the complete medication management system,
which is a critical MVP feature for Normogen.

Features Implemented:
- 7 fully functional API endpoints for medication CRUD operations
- Dose logging system (taken/skipped/missed)
- Real-time adherence calculation with configurable periods
- Multi-person support for families managing medications together
- Comprehensive security (JWT authentication, ownership verification)
- Audit logging for all operations

API Endpoints:
- POST   /api/medications          - Create medication
- GET    /api/medications          - List medications (by profile)
- GET    /api/medications/:id      - Get medication details
- PUT    /api/medications/:id      - Update medication
- DELETE /api/medications/:id      - Delete medication
- POST   /api/medications/:id/log  - Log dose
- GET    /api/medications/:id/adherence - Calculate adherence

Security:
- JWT authentication required for all endpoints
- User ownership verification on every request
- Profile ownership validation
- Audit logging for all CRUD operations

Multi-Person Support:
- Parents can manage children's medications
- Caregivers can track family members' meds

🔒 MVP Security Requirements

All Endpoints Must:

  1. Profile Isolation - Users can only access their profiles
  2. Permission Checks - Use existing permission middleware
  3. Audit Logging - Log all health data access
  4. Input Validation - Sanitize all health data

Special Considerations:

  • Children's data - Extra protection
  • Sharing - Explicit consent only
  • Reminders - No sensitive data in notifications
