Summary

The top bar of the admin and identity layout showed only "Admin / ". A detail page, such as an OAuth app, had no link back to its list.

The top bar now adds the sidebar section of the page as a middle crumb: "Admin / OAuth apps / Quilt Staging". The section link uses the same match that highlights the sidebar, so it works on every admin and identity page.

The middle crumb is left out when it would repeat another crumb:

• On the section's own list page (a GET of the list URL), where the title already names the section.
• When the section link goes to the same page as the first crumb (the dashboard, or Verification for a verifier who is not an admin).

A form that fails validation re-renders at the list URL by POST. That page keeps the section crumb.

admin_nav_groups is now built once per request. The sidebar, the command bar and the crumb all read it.

Tests

• spec/requests/admin_nav_spec.rb: three crumbs on an OAuth app page, no extra crumb on the list page, the crumb kept on a failed create, and no repeated crumb for a verifier.
• bundle exec rspec spec/requests: 1044 examples, 0 failures (before the second commit). admin_nav_spec and view_conventions_spec pass on the final commit.
• bin/rubocop on the changed Ruby files: no offenses.

Known issue, not from this branch: at 390px the copy button of the client ID on the detail page goes past the card edge.
