Slack 1.2.1: a clearer Send tile, and a send target you can see

The line above the message box said "Sending as Apollo Beach → #ops" with a
Lock button beside it. The box's own placeholder already reads "Message
#ops…" and the title bar already has a Lock, so both went. Quick replies
keeps its line: it has no placeholder, so that is the only place its target
is named.

The bigger thing behind it: until a transcript was clicked, a send went to
the first channel in the admin list whether or not that channel was on the
dashboard — so a board showing only #ops would quietly aim at #general. The
target now falls to the first configured channel whose transcript is
actually up, which with a single transcript is that one. Only when the page
shows no transcript at all does it fall back to the first configured
channel.

-- **Slack** — live transcripts of this location's Slack channels, plus
-  PIN-protected sending as the location. The ＋ picker lists one transcript
-  tile per configured channel, titled `#channel`, and two send surfaces (one
-  of each per dashboard): **Send message**, a free-text box with the admin's
-  quick emojis one press away, and **Quick replies**, a grid of preset
-  buttons. Both post to the channel of whichever transcript was clicked last
-  — its bottom edge lights up in the accent color — and to the first
-  configured channel until one is clicked. Messages arrive with avatars,
-  names and times, Slack's inline formatting and the workspace's custom
-  emoji; a right-click on one opens the reaction menu, and text size and
-  jump-to-latest sit in the title bar. Nothing leaves the machine until the
-  PIN is entered: one PIN unlocks every Slack tile on that dashboard page
-  until the auto-lock idles out, a reload asks again, and the lock button on
-  a send tile's title bar ends it early.
-  Admin config is in four groups: **Slack account** (the location account's
-  User OAuth Token — `xoxp-…`, so messages are literally from the campus —
-  or a bot token plus "Send as"), **Channels** (the joined channels to
-  follow, one transcript tile each), **Transcript** (refresh interval,
-  messages kept, thread replies) and **Sending** (the switch on the group's
-  title row, a 4–8 digit PIN, auto-lock minutes, quick replies one per line
-  as `Label | Message` — add `| #channel` to bind one to a channel — and up
-  to eight quick emojis).
-  Tile settings: avatars, timestamps, names and channel notices.
 - **Clock** — a big booth clock; also the smallest possible module and the
   reference for module authors.
