Add Clear Cache & Use Fallback button to Spotify settings

Always-visible button in Spotify API section that clears the OAuth
token cache, pauses enrichment, and switches to the configured
fallback metadata source. Also fixed the dashboard service card to
show the actual active source name (Spotify/iTunes/Deezer) instead
of always showing "Spotify" with an amber fallback indicator.
