fix(music): add spotify-tokener with Chromium for Partner API anonymous tokens

Spotify changed their API in Feb 2026 - playlists now require anonymous
tokens via the Partner API. The default anonymous token endpoint is
blocked from server IPs. Added a custom Dockerfile for spotify-tokener
with Chromium installed, and configured LavaSrc to use Partner API with
the tokener endpoint. Playlists now load successfully.
