feat: radio metadata (#352)

* feat: support dynamic metadata for internet radio stations

- Implemented `onMetadata` in `BaseMediaService` to extract "Artist - Title" info from ICY, ID3, and Vorbis streams.
- Added a fallback mechanism to periodically check HTTP headers (e.g., `icy-name`, `StreamTitle`) for radio metadata.
- Updated `PlayerControllerFragment` and `TrackInfoDialog` to display the station name alongside dynamic track information.
- Enhanced `TrackInfoDialog` layout to include a dedicated "Station" field for radio tracks.
- Modified `MappingUtil` to preserve station names in media metadata extras.

* fix crashing issue

* radio bob metadata works now. fix crashing issue

* Fixing unchecked operation warnings in SongHorizontalAdapter.java.

* optimizing a bit and better format for notification

* removed xml files affecting build and enviroment

* removed xml files affecting build and enviroment

* fix ui internet radio bottomview

* Revert "fix ui internet radio bottomview"

This reverts commit c237ed451ff436f4be964084b144d94f1ad37668.

* rebased to upstream/development and fixed metadata to show up for radio after the rebase

* misc.xml restored

* Apply suggestion from @eddyizm
