feat: gleichzeitige Aktualisierung von TDR-Werten über optimierten API-Handler

- API `/updateTdrSettingsDataAPIHandler` überarbeitet, um mehrere Werte in einem POST zu empfangen
- TDR-Dämpfung, Geschwindigkeit und Trigger werden nun in einem Schritt verarbeitet
- atomare Dateibearbeitung mit Bereinigung fehlerhafter Endzeilen (z. B. „12h)“)
- UI-Komponente `TdrEinstellung.tsx` angepasst auf POST mit Updates-Array
