Subject: [PATCH] Auto-Sync manager: exclude Last.fm Radio mirrors from the
 schedule board
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Last.fm Radio playlists are seed-track-specific similar-tracks
snapshots — they don't update on the Last.fm side once generated,
so scheduling one for auto-refresh would just re-discover the
same 25 tracks every interval. The mirror still exists (visible
in the Mirrored tab) so the user can pull the downloads, but it
doesn't belong on the schedule board.

``autoSyncCanSchedulePlaylist`` now rejects ``source='lastfm'``
alongside the existing ``file`` + ``beatport`` exclusions.
Cosmetic-only on the frontend; backend mirror creation +
Mirrored tab listing are unchanged.
