When a callsign resolves only to cty.dat (not on QRZ/HamQTH, or no lookup service
configured) — or the lookup errors — enrich the entry from the most recent QSO
already in the log with that call. Fills ONLY the fields the provider left empty
and the operator hasn't edited (name, QTH, grid, country, address, state, county,
lat/lon, zones, continent, email, QSL-via), so a real QRZ/HamQTH hit is never
overridden. Uses the worked-before entries (qso_date DESC, [0] = latest) via a
live ref so it works regardless of the lookup/worked-before debounce ordering.
