fix(ui-models): let a hand-declared route set its reasoning effort

The create card omitted the provider-level effort the editor card offers
for the same namespace, so a route declared through 添加自定义提供方 gained
a setting the moment it was reopened for editing — one the creating user
was never shown.

Both cards now render one shared control. The field, its vocabulary, and
the inherit-means-absent rule live with the control rather than in the
editor, which is what stops the two from drifting apart again.
