Enhance Pointer Events Handling with New Provider Component

- Added `PointerEventsProvider` to manage registered pointer events and provide context to child components.
- Updated `picker.tsx` to include the new provider, improving interaction handling by enabling dynamic event registration.
- Refactored existing logic to utilize the `PointerEventsContext`, enhancing the flexibility of pointer event management.

These changes improve the overall interaction capabilities within the application.
