Walkthrough

This PR upgrades react-native-reanimated to v4, replacing animated callbacks from runOnJS to scheduleOnRN via react-native-worklets. It migrates the bottom-sheet implementation from @discord/bottom-sheet to @gorhom/bottom-sheet, updates gesture handlers to the new Gesture API, and adjusts related type annotations and build configuration.

Added explicit type annotation to keyExtractor prop in BottomSheetFlatList. Updated mock in test setup.

Removed runOnJS imports; added scheduleOnRN from react-native-worklets.
Gesture Handler & Type Modernization app/containers/AudioPlayer/Seek.tsx, app/containers/RoomItem/interfaces.ts	Migrated from PanGestureHandler to new Gesture and GestureDetector API.

Poem

🐰 From v3 to v4, the animations flow,
scheduleOnRN makes the callbacks go,
Bottom sheets switch to gorhom's embrace,
New Gesture APIs set the pace,
Worklets bring order to the race! ✨
