feat: add route history, map controls, and geofence/FP management

- Position history with polyline trail and date range picker
  - Map style selector (standard, voyager, light, dark, satellite) persisted via SharedPreferences
  - Geofence and frequent place CRUD with info cards
  - Device banner with swipeable carousel
  - Refresh position button
  - Widget extraction: map controls, info cards, device banner, modal overlay
