Adds a "Cover art providers" section to the existing /admin/integrations
page with one card per registered provider (currently MBCAA + TheAudioDB).
Each card has:
- Provider name + capability badges (album cover · artist thumb · artist fanart)
- Status dot (green if enabled; muted if disabled)
- Enabled toggle + API key text field (only when requires_api_key)
- Save button (explicit save matches existing Lidarr card pattern)
- Test connection button (when testable) with inline ok/fail indicator
- Footer help line for TheAudioDB linking to the free key application
Save invalidates qk.coverProviders() always and qk.coverage() when
the PATCH response indicates version_bumped: true (so the coverage
gauge re-queries to show settled→with_art transitions on the next
scan).
API key field uses type=password with a placeholder that clarifies
the test-key fallback behaviour — never echoes back the stored key
(api_key_set bool from the GET response controls the "✓ Set"
indicator).
Local edit state is keyed by provider_id and survives query refetches
so in-flight edits aren't clobbered.
