feat(lib): surface server announcements as messages from "server"

An AdminMessage (server code 66) is how a server tells everyone it is going down, and the client dropped it on the floor. It now arrives in the private-message inbox as a message from the user "server", which is also the name the server's own command replies already come from, so every reader of that inbox shows it without a new API.
