connect login and room pages via logged in state

moving websocket into being managed by the room component.
if the partent would want access to "user signal" it can ask via
observer.
that would mean bidirectionality, and i already hear screeching of my
intuitions from react, but maybe that's ok and in react i would still
scope the websocket to the room page, plus callbacks
