feat(catalog): show agent verdicts per endpoint on the platform page

Fold callreview into one vote per team per endpoint over 90 days, publish it on
GET /catalog/platforms/{slug} as `reviews` past five teams, and render a quiet

proportion to the vote. Provider lines show the access chip only for exceptions,
and the phone-width tab bar and provider line no longer collapse.

Fragments: architecture/feedback.md, interface/dashboard.md, interface/api.md.
