Restructure kid dashboard: remove Talking, add Detection + Nearby Help

- Remove Talking page (duplicates AI Chat)
- Fix AI Chat: turn cap 7→15, personality-aware fallbacks
- Create standalone Detection page with YOLO body+face inference
- Create Nearby Help page merging Doctor Connect + Map with Leaflet
- Add lat/lng coordinates to all 22 doctor records
- Update quick links: Talking→Detection, Doctor→Nearby
- Update BottomNav: Map→Help
- Add permanent redirects for removed pages
- 36/36 tests pass
