feat(chase): the global hunt — new, or new plus unconfirmed, every category

The gap between worked and confirmed becomes visible everywhere. A Chase
setting on the DX Cluster page picks the mode; in new-plus-unconfirmed the
verdicts for DXCC/band/mode/slot, prefix, county and state are judged against
CONFIRMED-only ledgers built from the operator's chosen sources (LoTW, card,
eQSL, QRZ.com — HRDLog has no confirmation field in ADIF to offer), and a
need that exists only because a QSL never arrived is flagged Unconf: the
cluster and decode badges render it dimmed, the convention the grid hunt
introduced. The grid's own Chase selector folds into the global one; its
square-matching scope stays where it was, being grid-specific. One snapshot
key change rebuilds the cache when any of it flips.
