feat: Basis-DTOs, Service und Controller für automatische Metadatenverwaltung hinzugefügt

- Basis-DTOs für Lese-, Erstellungs- und Aktualisierungsvorgänge erstellt, um die Felder "hinzugefügt von", "hinzugefügt am", "geändert von" und "geändert am" automatisch über Middleware zu ergänzen.
- Diese Basiskomponenten in die Gruppenstruktur integriert.
