fix(autocall): the QSO in progress outranks the ladder

Six faults from an evening on 60 m, all in the same family: the engine
judging a station by what the log wants from it and forgetting what is
already under way.

- An exchange was abandoned mid-QSO. The reply lands in the same period
  the ladder is re-read, and that period was judged before the reply was
  taken into account, so a better-ranked caller took the slot from a
  station that had just come back to us. The answer is settled first now,
  and our own report counts as being inside the exchange too — which also
  protects a QSO the operator started by hand.
- A station just picked started with misses against it. Its transmit slot
  was unknown until a second decode, and with the parity unknown every
  period counted, including the one spent transmitting to it.
- The freed slot after "it is working somebody else" was thrown away: the
  period's decodes are in hand, so the next station is picked from them
  rather than fifteen seconds later. Never mid-over.
- Auto-call is never armed from a stored setting — not at launch, not on
  a profile switch. It is the one feature that puts the station on the
  air by itself and OpsLog starts with Windows.
- It says what it is waiting for: a wanted station in a QSO with somebody
  else now shows beside the Auto button instead of looking idle.
- Switching profile left the previous logbook's verdicts on screen. The
  worked-index, chase-new and the frontend's cached verdicts are dropped
  when the logbook changes.

FT decodes: distance column, a message addressed to you set whole in
green (the station you are calling keeps a tint — most of what it sends
goes to other people), badge order L / Wkd / WL, list cleared when the
RIG changes band.

Rotor: new world-map compass from EC1KD's design, with the Ultrabeam boom
and second lobe restored and the compact form preserved; the classic dial
is kept and Settings → Rotator chooses between them. Stop no longer
flickers on a rotor standing still — movement was inferred from a degree,
less than the jitter a controller reports at rest.
