feat(android): Search artists/albums as horizontal carousels

Audit v2 #14. Artists + Albums search sections were rendering as
plain vertical TextRows (name-only for artists, title+artist for
albums). Now match Flutter:

* Artists: horizontal LazyRow of ArtistCard (cover + name)
* Albums: horizontal LazyRow of AlbumCard (cover + title + artist)
* Section headers gain a count suffix ("Artists 12") matching
  Flutter's _SectionHeader pattern; also applied to the Tracks header
  for consistency.

Removed the now-unused TextRow helper.
