feat(webapp): let an environment JWT read a queue, as it already reads its metrics

The dashboard agent asks for a queue's live row — paused, depth, limit — through the environment JWT it exchanges for. The metrics route has accepted that JWT all along; the retrieve route answered 401, so the agent saw no queue at all.
