feat(hamlog): confirmation defaults and grid columns; drop a settings paragraph

Preferences → Confirmations gains a HAMLOG.online row, sent and received, with
the same defaults every other service has: a new QSO can start at N so the
backlog is meaningful from the first contact. The defaults reach it through a
new setExtraDefault — fill() writes through a pointer to a string field and
these two live in the extras map, which no pointer reaches.

The QSO grid gains four HAMLOG columns (status and date, both directions),
hidden by default: a column per service shown to everyone is how a grid becomes
unreadable.

And the paragraph explaining what "Sent" means is gone from that page.
