feat: Funktionalität des Datumsauswählers zum Eingabefeld hinzufügen

- Einen Datumsauswähler implementiert, der beim Fokussieren des Eingabefeldes und beim Klicken auf das Kalendersymbol geöffnet wird.
- Sicherstellt, dass das Eingabefeld keine manuelle Dateneingabe zulässt, während der Kalender weiterhin angezeigt werden kann.
- Das `onkeydown`-Ereignis verwendet, um manuelle Eingaben zu verhindern und die Datenauswahl ausschließlich über den Datumsauswähler zu ermöglichen.
