feat: docked watch-list panel, and auto-call learns the orthogonal markers

The watch list was a tab, and an operator working FT8 lives on the decodes
one: a station they had asked to be told about turned up on a screen they
were not looking at. The same answer is now docked in the widget strip,
above the tabs, reduced to what is worth acting on — on the air and still
needed, one row per band and mode, with the cluster's own NEW DXCC /
NEW BAND / NEW SLOT badge and a click that tunes. Off by default. The
"active and needed" answer costs a debounced query per visible slot, so it
is written once (lib/watchlistSpots) and the tab uses it too.

Auto-call:

- It answers a new prefix, county, state, square or park. Those markers
  are orthogonal to the entity, they ranked as nothing-needed, and the
  engine sat through a never-worked WPX prefix calling CQ. New rung at
  the foot of the ladder, gated by the chase switches the badges use —
  which meant making those switches portable, since the backend cannot
  read localStorage.
- It calls THROUGH a pileup. Giving up the moment the DX answered
  somebody else is precisely how a queue is not worked; the call and miss
  counters already bound the effort, and a station in mid-exchange is
  still never chosen as a new target.

The PSK Reporter panel now follows the station auto-call is waiting for:
the analysis takes a history query and a period or two to fill, so
starting it when the DX comes free is starting it too late.

Callbook lookup: a compound callsign with a page of its OWN keeps that
page's location. QRZ files HP/WE9G under exactly that form, with the
Panama square the station is operating from, and the rule that drops a
home address from a portable call was throwing it away. The record's own
country tells an operation's page from a home page.

Changelog: entries may open with [NEW], drawn as a pill in the What's new
dialog — a release is mostly fixes and the two or three genuinely new
things should not have to be found by reading all of it.
