Replace static import + createLayerComponent approach with dynamic import()
inside a useEffect, which ensures leaflet.gridlayer.googlemutant augments the
same L instance that's active at runtime. Add loading=async to Maps JS script.
Traffic is now toggled via a dedicated button (green when active) rather than
LayersControl, bypassing the react-leaflet layer lifecycle that caused the
constructor conflict.
