refactor(ui): improve intent handling and collection view state

- Update `handleStartIntent` and `handleStartPlayer` in `PlayerFragment` to ensure intents are only cleared if successfully handled and stations are valid.
- Refine star icon rendering in `CollectionAdapter` by clearing color filters when appropriate.
- Remove obsolete commented-out code and update log messages in `PlayerFragment`, `PlayerService`, and `LayoutHolder`.
- Uncomment maintenance preference updates in `SettingsFragment`.
- Reformat code for better readability in `CollectionAdapter`.
