Subject: [PATCH] Feature-Toggles, Administration, wiederkehrende Events und
 Event-Serien
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Administration & Rollenmanagement: Neuer Admin-Bereich mit Feature-Toggles
  und Sichtbarkeitseinstellungen pro Rolle (11 Toggles, 24 Visibility-Settings)
- AdministrationController mit eigenem Settings-Tab, aus SettingsController extrahiert
- Feature-Toggle-Guards in Controllers (Invitation, File, ListGenerator, Comment)
  und Views (events/show, events/edit, events/create)
- Setting::isFeatureEnabled() und isFeatureVisibleFor() Hilfsmethoden
- Wiederkehrende Trainings: Täglich/Wöchentlich/2-Wöchentlich mit Ende per
  Datum oder Anzahl (max. 52), Vorschau im Formular
- Event-Serien: Verknüpfung über event_series_id (UUID), Modal-Dialog beim
  Speichern und Löschen mit Optionen "nur dieses" / "alle folgenden"
- Löschen-Button direkt in der Event-Bearbeitung mit Serien-Dialog
- DemoDataSeeder: 4 Trainings als Serie mit gemeinsamer event_series_id
- Übersetzungen in allen 6 Sprachen (de, en, pl, ru, ar, tr)
