feat: playlist art fix + Play/Shuffle buttons in context header

- Fix playlist art: API returns images/images150/images300 arrays, not
  image_rectangle; update Rust model and Qt header to use images300 →
  images150 → images with fallback
- Add Play (▶) and Shuffle (⇄) buttons to the album/playlist header;
  Play starts from track 1, Shuffle enables shuffle mode and plays from
  a randomised position
