fix(playlist): suggestion rows match the normal track row (#980)

* fix(playlist): suggestion rows match the normal track row

The Suggested Songs table left the Favorite and Rating columns empty and
rendered only a single artist, so multi-artist tracks lost their split and
the blank columns read as a gap between Genre and Duration.

- Extract a shared PlaylistArtistCell that splits the OpenSubsonic artists
  array into individually navigable links; use it for both the playlist
  rows and the suggestions so a track reads the same before and after it is
  added.
- Show the real favorite heart and star rating in suggestion rows (global
  song operations), seeded from the song's own starred/userRating, removing
  the empty-column gap.
