feat(player-bar): album context menu on song title right-click (#512)

* feat(player-bar): album context menu on song title right-click

Right-clicking the track title in the player bar now opens the same
album context menu that album cards use (open, play next, enqueue,
go to artist, favorite, rate, share, download, add to playlist).

Mirrors the existing left-click behavior on the title, which already
navigates to the album. Suppressed for radio and preview, matching
the click handler.

MarqueeText gains an optional onContextMenu prop; PlayerBar builds a
SubsonicAlbum shape from currentTrack on demand.

* docs(changelog): add entry for PR #512 (player-bar title context menu)
