fix(ui): always order album tracks by disc and track number (fixes #3720) (#3975)

* fix(ui): ensure album tracks are always ordered by disc and track number (fixes #3720)

* refactor(ui): remove obsolete release date grouping logic from SongDatagrid and AlbumSongs

* fix(ui): ensure correct album track ordering in context menu and play button

* fix: Update album sort to use album_id instead of release_date

* refactor: Adjust filters in PlayButton and AlbumContextMenu

* fix: correct typo in comment regarding participants in GetMissingAndMatching function

* fix: prevent visual separation of tracks on same disc

Removes the leftover `releaseDate` check from the `firstTracksOfDiscs` calculation in `SongDatagridBody`. This check caused unnecessary `DiscSubtitleRow` insertions when tracks on the same disc had different release dates, leading to an incorrect visual grouping that resembled a multi-disc layout.

This change ensures disc subtitles are only shown when the actual `discNumber` changes, correcting the UI presentation issue reported in issue #3720 after PR #3975.

* fix: remove remaining releaseDate references in SongDatagrid

Cleaned up leftover `releaseDate` references in `SongDatagrid.jsx`:

- Removed `releaseDate` parameter and usage from `handlePlaySubset` in `DiscSubtitleRow`.

- Removed `releaseDate` prop passed to `AlbumContextMenu` in `DiscSubtitleRow`.

- Removed `releaseDate` from the drag item data in `SongDatagridRow`.

- Removed `releaseDate` parameter and the corresponding `else` block from the `playSubset` function in `SongDatagridBody`.

This ensures the component consistently uses `discNumber` for grouping and playback actions initiated from the disc subtitle, fully resolving the inconsistencies related to issue #3720.
