Fix access check form: use GET so results render

The access check form POSTed and re-rendered :new with a 200 HTML
response, which Turbo rejects ("Form responses must redirect to
another location"), so the result panel never appeared. Since the
check is a read-only query, switch to a GET form and fold the lookup
into the new action. Results are now bookmarkable via the URL.

Bump version to 0.16.2.
