### Rekapitulation zum teilweisen Ersetzen

Zusammengefasst, um Teil-Ersetzungen vorzunehmen:

* (Optional) verwenden Sie `PATCH` statt `PUT`.
* Lesen Sie die bereits gespeicherten Daten aus.
* Fügen Sie diese in ein Pydantic-Modell ein.
* Erzeugen Sie aus dem empfangenen Modell ein `dict` ohne Defaultwerte (mittels `exclude_unset`).
