fix(chase-new): one badge, filters, a way in and a way out — and the frequency

Four things from an operator's first look at the panel, and one of them was
mine.

The frequency column showed "—" on every row. pskr.Spot.FreqHz was declared
and documented in one edit and never assigned in the next, so the payload's
"f" was parsed and dropped. A click therefore filled the callsign and left
the rig where it was, which is half the point of the panel. Assigned, with a
test that runs a real payload through and checks the value survives into the
Spot — the field being declared is what made it look done.

A row now carries ONE indication instead of stacking them. A station can be a
new band and a new prefix at once; the row says the first that matters, in the
order that would make an operator leave what they are doing: entity, band,
mode, slot, then prefix, then square. Two badges on one line made the list
unreadable at a glance, which is the only thing it is for.

Each category has a filter chip in the header, in its own colour, remembered
across sessions. A toolbar button shows the panel and a cross closes it — the
same split the Super Check Partial panel uses, where the setting decides
whether the feature exists and the button whether it is on screen.

The panel is wider and the country column gets what is left, which is more
than it was now that a row carries one badge.
