RBAC: drop Wildcards group from Roles page client-side mapping

Pairs with the cloud-side change that removes `admin`, `read:all`,
and `write:all` from PERMISSION_CATALOGUE. With no catalogue entry
sitting in the Wildcards group, the corresponding entries in the
client-side PERMISSION_GROUP_BY_NAME map are dead and the group is
removed from GROUP_ORDER.
