refactor: Recoil durch Redux ersetzt und Fehler behoben

- Entfernt `useRecoilState(mapLayersState)` und durch `useSelector(selectMapLayersState)` ersetzt.
- Alle `setMapLayersVisibility` durch `dispatch(setLayerVisibility(...))` ersetzt.
- LocalStorage-Handling für `mapLayersVisibility` mit Redux umgesetzt.
- Fehler "setMapLayersVisibility is not defined" behoben, indem `dispatch` verwendet wurde.
- Sicherstellung, dass `mapLayersSlice` im Redux-Store registriert ist.
