Auswahl eines Bereichs mit Umschalt+Klick in der Wiedergabeliste und der Titelliste (Web & Desktop)

In playlist, album and favorites track lists, selecting multiple tracks currently requires clicking each checkbox individually. For lists with hundreds of tracks, this makes bulk actions (add to playlist, remove, add to queue) slow and error-prone.

Proposed behavior (following the standard file-manager convention):

1. Click a track's checkbox or row to set the selection anchor.

2. Shift+Click on another track selects the whole contiguous range between the anchor and that track.

3. Ctrl/Cmd+Click toggles a single track without changing the rest of the selection.

4. Optional: Shift+Arrow Up/Down extends the selection via keyboard, and Cmd/Ctrl+A selects all.

5. The bulk-action bar updates its counter ("N tracks selected") and stays visible while scrolling.

Why: It matches the behavior of Finder, Explorer and other music clients. It saves many clicks when cleaning up or reorganizing large playlists. It also improves keyboard accessibility.

Environment: Deezer Desktop 8.0.0 (8.0.0), macOS 26.7.1 (25G241). The request applies to the web player too.
