Fix: Messkurven-Modal (ISO/RSL) lädt Kurve automatisch, setzt Dropdown & DateRangePicker korrekt zurück

- Dropdown für Messkurven (ISO/RSL) wird beim Öffnen auf 'Alle Messwerte' (DIA0) gesetzt
- Messkurve wird beim Öffnen des Modals automatisch geladen
- Beim Schließen werden vonDatum, bisDatum, Dropdown und DateRangePicker zurückgesetzt
- Gleiches Verhalten für ISO- und RSL/Loop-Modal
