Add Medicine and Activity trackers with voice command support

Added new tracking pages:
- Medicine tracker: track medication name, dosage, unit, route, and reason
- Activity tracker: track play, exercise, walks, music, reading, tummy time, etc.
- Both pages follow existing tracker patterns with recent activities list

Voice command improvements:
- Updated voice classification to support medicine and activity types
- Added detailed extraction fields for medicine (medicineName, dosage, unit, route, reason)
- Added detailed extraction fields for activity (activityType, duration, description)
- Enhanced unknown intent dialog with manual tracker selection
- Updated tracker options to match implemented pages (removed milestone)

Backend changes:
- Added MEDICINE and ACTIVITY to ActivityType enum
- Created migration V013 to add medicine/activity to database CHECK constraint
- Updated voice service prompts to include medicine and activity extraction

Frontend changes:
- Created /track/medicine page with full CRUD operations
- Created /track/activity page with full CRUD operations
- Added Medicine card to /track page with MedicalServices icon
- Updated VoiceFloatingButton unknown dialog with 4 tracker options
