fix: keep SUPER_ADMIN_GROUP as app_super_admin so resource auto-provisioning nesting works

api_directory_admin nests permission.SUPER_ADMIN_GROUP into every new resource's
_admin group. Changing it to the not-yet-existing 'god_admin' made that nesting
no-op, leaving the creator as the sole member (so the access_request test's
beforeAll could not remove the last member of a groupOfNames). Revert it to
'app_super_admin' and recognize 'god_admin' separately in isSuperAdmin + isAdmin.
