First service of the per-profile playlist-auth feature. Each profile connects
its OWN Spotify account through the shared (admin's) app, getting its own token;
used for that profile's playlist reads. Admin + unconnected profiles + all
background workers keep using the global/admin client — fully non-regressive.
- Shared-app OAuth: get_spotify_client_for_profile + the /auth/spotify init &
callback now use the GLOBAL app creds (falling back from any legacy per-profile
app creds) with the profile's own token cache, and show_dialog=true forces the
account chooser so a user can't silently inherit the admin's Spotify session.
The builder gates on the profile's own token cache existing — no cache → global.
- My Accounts modal (new, all-profile-accessible via the profile bar): one-click
Connect/Disconnect Spotify + connection status (account name). GET
/api/profiles/me/connections + POST .../spotify/disconnect; admin's Spotify is
read-only here (managed in Settings).
- Wired the request-scoped reads to the per-profile client: the playlist LIST,
the playlist TRACKS view, liked-songs count, and user info — so a connected
user sees and opens THEIR OWN (incl. private) playlists, not the admin's.
Tests: builder falls back to the global client for admin/None/unconnected (the
non-regression guarantee); connections status reports unconnected; admin
disconnect rejected. 124 profile/spotify/gate/integrity tests pass.
Still on the global account (next step): sync/download jobs run in background
workers with no profile context — stamping the requesting profile onto the job
is the remaining wiring. Other services (Tidal/Deezer/Qobuz/Last.fm/ListenBrainz)
follow this same pattern.
