Replace custom View-based bottom sheet with @gorhom/bottom-sheet:
- Native gesture-driven drag, snap points, pan-down-to-close
- Proper safe area handling built in
- Wrap app with GestureHandlerRootView
- Add react-native-reanimated plugin to Expo config
Adds react-native-reanimated and react-native-gesture-handler as
native dependencies (requires new EAS build).
