Track subscribed channels in RMQBackend and re-apply queue_bind on every fresh consumer channel so messages keep flowing after a disconnect. A new _sub_lock serializes subscribe/unsubscribe with the rebind loop to prevent concurrent set mutation and duplicate binds on a mid-setup channel.

This change is needed because when Rabbit services restart the reconnect does not re-bind since the subscription groups are still there, it silently passes.
