bus, webui, cli: the Console shows the reply to a web send (#1575)

Row 81. The broker gains a `replies` read verb for human and reader
sessions: `{id}`, a message UUID, returns that business's messages whose
in_reply_to is the id, oldest first, at most 50, and writes no
deliveries row, so the reply still reaches the next `mosaic talk`. An
unknown id refuses message-not-found. The Console serves it through
BUS_VERBS with an id check, and the Sent receipt shows the replies to a
web send. The cli's talk timeout message and README now say the reply
may still come and the next `mosaic talk` prints it.

Dewey's round 2, candidate manifest 3ce7527f, base 1e5f5958, a rebase
after row 61. Approved by Darkwing (27783 round 1, 27821 round 2).
Sage's gate green 19:25:18Z to 19:30:39Z. Live at the next bus restart
(the broker verb) and Console restart (the view), bus first.
