Profiles: label the no-auth Spotify composite everywhere it's shown

Follow-up to the modal fix: the sidebar Service Status + dashboard service card
also mislabeled "Spotify (no auth)" as plain "Spotify". They read the status
`source`, which came straight from metadata.fallback_source ('spotify') with no
awareness of the metadata.spotify_free flag.

- get_primary_source_status now reports a DISPLAY source of 'spotify_free' when
  fallback_source='spotify' + metadata.spotify_free is set (the raw 'spotify' is
  still used for the auth/connected checks), and treats the free path's
  availability as "connected" so the dot isn't falsely red on a no-auth setup.
- getMetadataSourceLabel maps 'spotify_free' → "Spotify (no auth)"; the status
  presentation treats spotify_free as part of the Spotify family (session /
  rate-limit / cooldown display still work). Added a SOURCE_LABELS entry.
- testDashboardConnection normalizes spotify_free → spotify (the only logic
  consumer of the source value — the dashboard Test button).

Routing is unchanged (the real source stays 'spotify' + free flag); this is
purely the display layer. Settings was always correct. 64 integrity tests pass;
the 2 failing soundcloud tests are pre-existing (confirmed identical on a clean
tree).
