f804791 added app/routes/doormile.py against a base that predated the
Valhalla work. Rebasing it onto 9ef2f61 rewires it to what is really
running, without disturbing anything the server had: the RoadMatrix
probe, road_backend_status and the VALHALLA_URL switch are all intact.
The one thing the endpoint depends on is unchanged --
optimize_provider_payload(orders, start_coords=None) has the same
signature in the server's optimizer as in the version it was written
against -- so passing the kitchen through as the run's start still
works. Tests re-run against the server's code: all pass.
