fix(cluster): slot colour apart from POTA, chips match badges, NEW CALL filter works

Three from review. Aqua for NEW SLOT sat right next to the POTA green — it is
now the sky cyan the panadapter palette has shipped for new-slot all along.
The NEW COUNTY chip was green while its badge is violet, and NEW SLOT's chip
was still caution yellow: chips now carry the badge's own colour (color-mix for
the muted border/背景), because a filter that does not look like what it selects
has to be learned twice.

And the NEW CALL chip matched only the DISPLAYED status, which is manufactured
by the slot-highlight option — with that option off the chip matched nothing
and read as broken. It now filters on the fact itself (worked_slot false), so
it works either way.
