[FEAT] Added destination Trash

- Implemented MediaProvider.restore functionality.
- Introduced TrashViewModel.
- Added trash screen for managing deleted items.

[REFACTOR] Extracted common functionality to MainViewModel
- Moved FileActions and SelectionTracker from TimelineViewModel to a new superclass called MainViewModel.
- This refactor was necessary to centralize shared functionalities among various view models.

[FEAT] Added rudimentary implementation of Viewer Destination
- Basic implementation to support viewing files in the new destination.
