feat: filter cluster spots on new POTA and new county

The grid already badges them; only the filter was missing.

They are not entity statuses — a new park or county is another dimension of the
same spot — so the filter key is now a superset of the status, and matching is
an OR across all of them, as it already was for a previously-worked callsign.
The chips carry the colours their badges use in the grid: a filter that does not
look like what it selects has to be learned twice.
