Changes:
- Fix nutrition service: add is_active column and Pydantic validation for UUID/datetime
- Add location-based alerts feature: users can now see alerts within 1km radius
- Fix CORS and response serialization in nutrition service
- Add getCurrentLocation() and loadAlertsNearby() functions
- Improve UI for nearby alerts display with distance and response count
