The runtime list was exported but only its type was used, so the type is
now written out. The form's pure logic (draft, checks, request body,
change detection) gets tests under node's built-in runner, run by the
existing swarm-ui check.
The classifier settings page showed model and effort only, so the API-key
or ACP runtime could be switched only through a raw API call. It now has a
runtime select, and under ACP the provider's URL, model and prices. A PUT
carries the provider only on the ACP runtime, so the stored record stays
for a switch back. Closes#5249
A classifier settings panel under the try-out form reads and saves the model,
effort and how many requested reviews run at once through the settings route.
A save replaces all three; a refused one shows the route's reason and leaves
the form as typed. There is no API key field.
