bsncubed 7bbda0a1e8 Step 7.5a: Spotify client credentials in config/UI, write-only secrets
- Core config: cfg_mark_secret(group, key). GET /api/config returns ""
  for secret keys; a POST with "" keeps the stored value, null clears it;
  cfg_get() returns the real value. Documented in aes67-core-base.md.
- source.spotify_client_id / spotify_client_secret (secret write-only):
  each user's own Spotify developer app, needed by the maintained cspot
  fork (philippe44/cspot) since Spotify's 2025 API restrictions.
- UI: client ID field, password field for the secret ("leave empty to
  keep"), link to developer.spotify.com; enabled for spotify/auto modes.
- status.spotify_state: "no client credentials" while either is missing.
- Verified: secret never appears in GET; UI-style re-save keeps it;
  survives reboot; null clears it.
