The feed hears new posts as they come

decePub opens PrivaPub's streaming API (one WebSocket for the persona, its
token given as the socket's protocol, never in a URL) and subscribes to the
stream of the feed in view: home, a list, local, federated, a hashtag or
notifications. New posts wait behind the "new" button as polled ones did;
a deletion or an edit applies at once. Polling stays for the feeds PrivaPub
does not stream and for any feed while the socket is down, which opens again
after a pause growing to a minute. The e2e test sees a post made elsewhere
in seconds and its deletion take the card away.
