feat: GisStationsStaticDistrict in Redux-Store integriert

- WebService-Endpoint für GisStationsStaticDistrict angebunden
- Daten beim Start der Anwendung automatisch geladen und in Redux gespeichert
- UI (DataSheet) verwendet die Daten direkt aus dem Redux-Store
- Fehlerhandling und Initialzustand in Redux-Slice verbessert
- Alte lokale Fetch-Logik entfernt, zentrale Datenhaltung über Redux
