The colour picker recolours the London to Paris route already on the map, applying one value without recalculating anything.

• geocodeOne returns one Waypoint per endpoint, which calculateRoute takes as it stands, once, at startup.
• RoutingModule.updateConfig takes a partial config, so color is the whole change. There is no second request and no MapLibre paint property to set by hand.
