- Archive the completed observability-service-registry SDD change into
openspec/changes/archive/ (delivered across 5 slices; only
jellyfin-service-registry remains active).

versioned alongside the code, and add the regenerated map pairs repo-wide.
- Add get_api_key() and require_api_key() to auth.py
- Add generic key-value settings storage to SettingsStore
- Add test_api_key_auth to verify the implementation
- Uses secrets.compare_digest for timing-safe comparison
- Auto-generates API key on first use and stores in settings DB
