feat(qsl): HAMLOG.online in the Edit QSO confirmations

The QSL Info tab knew every upload service except the newest one, so a
contact uploaded to HAMLOG.online could be edited everywhere but there.
It is stored in the ADIF extras rather than QSO columns -- like the
OpsLog card -- hence a channel of its own instead of a CONFIRMATIONS
entry, but it gets the ordinary sent/received/date editor because it
behaves like QRZ.com or Club Log, not like a printed card.

Its four columns move from the QSL group to Uploads for the same reason:
QSL is for cards, an upload service belongs with the upload services.
