Subject: [PATCH] =?UTF-8?q?Fix:=20Verschlei=C3=9Fteil-Formular=20Datumsval?=
 =?UTF-8?q?idierung=20und=20Schriftfarbe?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- installDate Schema akzeptiert jetzt YYYY-MM-DD Format (HTML date input)
- maintenanceHistorySchema date akzeptiert jetzt YYYY-MM-DD Format
- Transform konvertiert Datumsstrings automatisch zu Date-Objekten
- API-Routes verwenden validierte Date-Objekte direkt
- Alle Formularfelder haben jetzt schwarze Schriftfarbe (text-black)
- Optional-Felder werden getrimmt (brand, model, notes)
