Live evidence: a 574-track add reported success (added=574, no exception)
but Music Assistant's own playlist view still showed only 35 tracks
afterward - the previous count, unchanged. Apple's own developer community
documents this exact failure mode for the library-playlist track-add
endpoint: large batches can report success while the tracks never
actually land, completely silently, with no official batch size limit
published. MA's add_playlist_tracks is itself fire-and-forget ("creates
background tasks to process the action"), so neither side can detect a
silent failure after the fact.

Chunks the add into batches of 25 (matching the batching precedent already
used for the Qobuz wishlist push elsewhere in this file) with a 1s delay
between batches, to give each batch a much better chance of actually
persisting. Not a guaranteed fix - Apple's failures are reported as
inconsistent even at moderate sizes - but the sync recomputes its diff
fresh every run, so anything that still doesn't persist will simply
reappear as "to add" on the next sync rather than being lost.
