- Überriding der DeleteAsync-Methode hinzugefügt, um verwandte ModuleOfUser- und GroupOfUser-Entitäten zu behandeln. - Sicherstellung der Entfernung verwandter Datensätze bei der Löschung eines Benutzers. - TODO-Kommentar hinzugefügt, um zu empfehlen, .OnDelete(DeleteBehavior.ClientCascade) im DbContext für ein verbessertes Verhalten zu verwenden.

//TODO: DeleteBehavior.Restrict (see example comment below) is not working, probably due to table relationships. Because it tries to delete, for example, User first and then GroupOfUser. However, since GroupOfUser is not deleted while Users is deleted, the error is thrown because of the table relationship. Apply this approach after finding the solution.
