Phase 3: Integrate Google Takeout context into InsightGenerator

- Updated InsightGenerator struct with calendar, location, and search DAOs
- Implemented hybrid context gathering methods:
  * gather_calendar_context(): ±7 days with semantic ranking
  * gather_location_context(): ±30 min with GPS proximity check
  * gather_search_context(): ±30 days semantic search
- Added haversine_distance() utility for GPS calculations
- Updated generate_insight_for_photo_with_model() to use multi-source context
- Combined all context sources (SMS + Calendar + Location + Search) with equal weight
- Initialized new DAOs in AppState (both default and test implementations)
- All contexts are optional (graceful degradation if data missing)
