The Models editor card curated its pi-ai fields by what every route has,
so `displayName` and `api` — the two a hand-declared route names for
itself — were asked for at creation and then reachable only through
settings.yaml. The editor now renders both for a route the directory
reports as declared, from the same namespace schema the create card
reads. A catalog route gets neither: it defaults its name from its
catalog entry, and its models each carry their own protocol, so a
route-level one could only override all of them.
Clearing the name unsets it and the route falls back to its id, which is
what the field's placeholder shows; storing the empty string would be
refused by the adapter. A declared profile naming no protocol selects
nothing rather than reading as if it had picked the first choice.
The Provider ID stays fixed: it is the settings dict key, it is
referenced from `agent-default-model` and every logged request header,
and it is the stem of a credential reference the page can never read
back to move.
