Reported by VK4DX with the case that names itself: YB confirmed on 20m
digital, painted blue, because one unconfirmed YB station had also been
worked on that slot.
The ladder ran call_c > call_w > dxcc_c > dxcc_w, so a callsign worked and
not confirmed beat an entity CONFIRMED on the same band and mode. The grid
answers 'what do I still need here', and a confirmed entity needs nothing
whoever was worked afterwards — so the order is now call_c > dxcc_c >
call_w > dxcc_w.
Two things made it easy to get wrong, and both are fixed rather than
merely corrected. The code was a run of assignments where the later test
silently overwrote the earlier, so 'call worked' erased 'entity
confirmed'; it now takes the maximum. And the rule lived inside a scan
loop where nothing could reach it, so it is lifted into bandStatusCode
with a table test — including this exact case, and one that fails if
anybody reorders the constants.
