- ICRUDService angepasst, um von IReadService zu erben, um die Wiederverwendbarkeit von Lesevorgängen zu fördern - ICRUDService um `CreateAsync`- und `UpdateAsync`-Methoden mit geeigneten Rückgabetypen ergänzt - Konsistenz gewährleistet durch Durchsetzung von IUnique<TId>-Einschränkungen für DTOs und Entitäten
