Take the jvui that draws emoji in colour, and put the pin back

jvui draws a colour emoji as a picture now rather than trying to make a
128-pixel bitmap strike behave as a fallback font, so the react, reply and
edit chips, the reaction tallies and every emoji inside a message come out
in colour instead of as an outline. And a scroll reserves the strip its bar
is painted in, so the last characters of a wrapped line are no longer under
it — the conversation list is where that showed, a card's worth of text
ending in a grey bar.

The pin also goes back to gitlab. It was pointed at a local worktree while
that branch was unpushable, and the scratch path went out with the last
push — a URL under /tmp that exists on exactly one machine, which is not a
pin at all. deps.edn's sha moves with it; the two name the same rev for the
reason the note above them gives.
