fix: Resolve scrolling and audio playback issues

- Fix scrolling on Music Storage page by adding proper overflow handling
- Add height constraints and flex layout for better tab panel scrolling
- Update streaming endpoint to use presigned URLs instead of direct URLs
- Improve audio error handling with better error messages
- Update MusicPlayer component with dark theme styling
- Add loading indicators and error states for better UX
- Fix audio playback for files synced from S3 subdirectories

The Music Storage page now has proper scrolling behavior and
audio playback should work correctly for all music files.
