feat(hamlog): show what the confirmation import did, and export what it could not place

The import printed four numbers and left nothing behind. 1106 matched
and 395 unmatched out of 1501 is not a report: the operator cannot see
which contacts were confirmed, nor work through the discrepancies.

Two additions. The Results view is now filled with the confirmed
contacts, flagged new entity/band/mode/slot against what LoTW and paper
QSL already confirm -- the only sense in which a HAMLOG confirmation
changes anything. And the unmatched ones can be written out as ADIF,
because a few hundred of them are a list to open and compare, not
something to read in a log window.
