feat(ui): the FT decodes panel, two DXHunter themes, and the maps

Decodes:
- one click SELECTS, two transmit. A single click handed the decode
  straight to WSJT-X as a reply, so brushing a row while reading the
  band started calling a station.
- the list empties for a receiver that changes band, and a receiver
  column appears when more than one is feeding one merged list.
- the period clock turns red while transmitting: it is the one thing on
  the screen that moves, so it is where the eye already is.
- a WL badge, after the LoTW "L" — one letter, always in the same
  place, so the column does not shift from row to row.
- the auto-call switch, its target and its count, and the chase list:
  naming the station you are waiting for is done while watching the
  band, not in a settings tree.

Themes: DXHunter's slate with its own blue, and the same slate with
OpsLog's orange. Counted across its sources rather than guessed from
one panel — blue is 132 uses to violet's 25, and the violet is the PSK
Reporter panel alone.

Watchlist: drawn as DXHunter draws it — the callsign in the interface
font rather than monospaced, which is the difference that shows with
the two windows side by side.

FT Map: arcs no longer run off the side of the map. The map shows one
world, and a path crossing the antimeridian was drawn past 180° into
the blank space beside it — from VK that is most of them.

Cluster: "superfox", "fox/hound" and "F/H" in a comment are read as
FT8. They are WSJT-X's DXpedition transmit modes, and the comment fell
through to the band plan and came out DATA — which then decided the
band+mode verdict.

A decoder is named by what it IS: Nexus sends its packets as "Tempo",
the engine inside it, and OpsLog showed a program nobody has heard of.
