fix: exclude error channels from appliance lifecycle roles

An `error_status` sensor matches the `*_status` allowlist segment, so a
fault channel reporting `active` painted the marker as working, and with a
live `status` peer the winner depended on registry order. `error` joins the
same stop-list as connectivity telemetry (code review #164, finding M1); the
connectivity rejection unit now carries an active fault channel alongside a
real lifecycle peer.
