feat: Remove Player tab and use persistent player across app

- Remove Player tab from Music Storage page
- Update play buttons to use persistent player instead of embedded player
- Add persistent player to Music Storage page for consistent experience
- Convert MusicFile objects to Song objects for persistent player compatibility
- Ensure music playback works seamlessly across both main view and Music Storage
- Create unified music playback experience throughout the application

Now users have a consistent music player experience across all pages
with the floating persistent player at the bottom of the screen.
