Subject: [PATCH] Refactor User and UserDto to inherit from UserBase
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Aktualisierte `User` und `UserDto` Klassen um von einer neuen `UserBase` Klasse zu erben.
- Verschieben der Eigenschaften `Vorname`, `Email` und `Alter` zu `UserBase`.
- Implementierung der überschriebenen Methoden `GetHashCode` und `Equals` sowohl in `User` als auch in `UserDto`, um die Eigenschaften der Basisklasse zu nutzen.
