Fix slow Tidal playlist loading — metadata only, no track fetching

Browse source 
get_user_playlists_metadata_only() was fetching full track lists for
every playlist sequentially (1+ API calls per playlist with 1s sleep
between pagination pages). For 20+ playlists this took 30-60 seconds.

Now returns only metadata (name, ID, track count, image) from a
single V2 API call. Track count comes from the numberOfTracks
attribute. Tracks are fetched on-demand when the user selects a
specific playlist to sync/mirror via the existing get_playlist()
endpoint.
