feat: Recoil-State 'selectedAreaState' durch Redux ersetzt

- Redux-Slice 'selectedAreaSlice' erstellt mit set/clear Funktionen
- DataSheet.js verwendet dispatch(setSelectedArea(...)) für Dropdown-Auswahl
- MapComponent.js liest Bereichsauswahl über useSelector aus Redux Store
- Recoil-Importe entfernt, Zustand zentralisiert

+- Recoil-State `selectedAreaState` vollständig entfernt
+- Umstellung auf Redux:
+  - `selectedAreaSlice.js` → zentrale Steuerung des Bereichs (Area)
+  - `DataSheet.js` – setzt `setSelectedArea(...)` über Redux
+  - `MapComponent.js` – liest `selectedArea` aus Redux und zentriert Karte
