iOS 1.0.8: stem playlists, karaoke softness slider in lyrics

- Playlists tab splits into Plex and Stem. Plex playlists are unchanged and
  now show their custom poster when one is set.
- Stem playlists live on the device; each song keeps its own mix. Add from
  any song or collection menu, or copy a whole Plex playlist.
- Queue items can carry a mix, which wins over the song's saved mix.
- Softness slider under the Vocals picker in lyrics when set to Soft.

 `ios/` is a SwiftUI port of the Android app with the same features, plus CarPlay (browse tabs, Now Playing with Vocals and Mix buttons) and Siri ("play X in Stemify"). iOS 17 or newer.
 
+On top of the Android features: the Save chip in the mixer remembers a mix for that song and puts it back every time it plays, and the mic button turns on karaoke mode (vocals muted on every song, synced lyrics from [LRCLIB](https://lrclib.net) on Now Playing; tap a line to jump to it).
