perf(lotw): stop asking for the QSL details by default

A tester compared LogHX's two download options on the same account: two minutes
for the confirmations, twenty for the confirmations with QSO details. OpsLog was
always sending qso_qsldetail=yes — LogHX's slow option — which is the whole of
the wait people were reporting.

Marking a confirmation needs call, date, band and mode; the detail adds the QSL
date and the station's grid, state and county. Now a choice, off by default, and
forced on when the download is also ADDING the QSOs it cannot find — the one
case where those fields have no other source.
