Fix login data structure and improve voice input UX

- Fix login endpoint to return families as array of objects instead of strings
- Update auth interface to match /auth/me endpoint structure
- Add silence detection to voice input (auto-stop after 1.5s)
- Add comprehensive status messages to voice modal (Listening, Understanding, Saving)
- Unify voice input flow to use MediaRecorder + backend for all platforms
- Add null checks to prevent tracking page crashes from invalid data
- Wait for auth completion before loading family data in HomePage
