feat(lotw): let the download cover every callsign on the account

The download passes qso_owncall so one profile does not pull another's
confirmations. That scope also hides them: a QSO made as F4BPO/P is confirmed at
LoTW and can never come back to an F4BPO profile, so it stays unconfirmed here
for good while the ARRL counts it — found while reconciling a DXCC account
against the panel, where it was the whole of the CW gap (Jersey, worked as
F4BPO/P).

Off by default: the scope is right for anyone whose profiles are separate
stations.
