Daniel e9931d82af Refactor: Zentralisiertes Admin-Login im Top-Menü
- Admin-Login aus 3 Plugins (Soundboard, Streaming, Game Library) entfernt
- Zentraler 🔒/🔓 Button im Header mit Login-Modal
- isAdmin wird als Prop an alle Plugins weitergegeben
- Settings-Buttons (Gear-Icons) nur sichtbar wenn eingeloggt
- Alle Plugins nutzen weiterhin den shared admin-Cookie für Operationen
- Login/Logout-Formulare und Buttons aus Plugin-Panels entfernt
