Lists the models of one backend with their prices and approval requirement: each catalog
entry, and the default first when the catalog does not contain it (Claude Code lists none).
Approval is evaluated for the listed name (for the default, the name it runs as);
an entry naming the id covers its effort variants, and one naming a single variant
(<id>-<effort>) applies when that variant runs.
