Dial a route at the machine port its module's placement assigned, from the mesh-sdk whose plans carry it (issue 774, research 072 row 34)

route-proxy from plans dialled every route at the software's own port: gitea at 127.0.0.1:3000
(published at 20000) and grafana on ace at 3000 (published at 20012), and public sites answered
502. The proxy already reaches a module beside it over loopback and one elsewhere at the plan's
address; the plan now carries the assigned port, and a test composes the plan with the SDK and
reads it as the proxy does, so the two cannot drift again.

The controller, NATS-native: no piece moves; route-proxy only.
