401 auto re-login, My Location via native GPS, edge-to-edge, brain-car icon

- Client: onUnauthorized hook; 401 clears the token and (in-app) bounces to sign-in
- Map: "My location" uses the native UserLocation fix + flyTo; safe-area insets on
  the floating status bar / controls
- Enable edgeToEdgeEnabled (Android 15 forces it) so headers/back-arrow sit correctly
- App icon: brain-car launcher + adaptive icon
