Fix Leaflet map initialization: prevent DOM errors and ensure robust container checks

- Refactored initializeMap to accept the DOM node instead of the ref object
- Updated all checks to use the DOM node directly
- Improved useInitializeMap to only call initializeMap when the container is ready
- Prevents "mapRef.current ist nicht definiert oder nicht im DOM" errors
- Ensures map is only initialized when the container is attached
