IGDB auto-enrichment: Server-Start + Frontend auto-trigger

- Server enriched bestehende User beim Plugin-Start automatisch (fire-and-forget)
- Frontend triggert IGDB-Enrichment automatisch beim Öffnen einer User-Bibliothek
- Reduzierte Log-Ausgabe (kein Spam pro Cache-Hit mehr)
- IGDB-Button zeigt Lade-Animation während Enrichment
