feat(media-player): enhancement

[alperozturk96]

Original PR: #16116

This merge request adds a persistent "queue" / playlist feature to the Nextcloud Media Player and implements a set of frequently requested playback behaviors and UI improvements:

• Shuffle mode (randomize playback order)
• Repeat modes (repeat one / repeat all / off)
• Automatically play the next file when the current media ends (so folders with mixed content will behave as playlists containing only media files)
• Automatic filtering to exclude non-media files when generating a playlist from a folder
• Improved media player notification controls while the app is minimized (skip to next / previous, play/pause)
  The proposed implementation has been used in the HiDrive application for a long time.

@AlexViseven Can you update the license headers? We are using AGPL-3.0-or-later.

I think BackgroundPlayerService is becomes unnecessary after this enhancement?

blue-Light-Screenshot test failed, but no output was generated. Maybe a preliminary stage failed.
