chore: release v0.24.9

Replaces the four fixed rules with the model Logger32 uses and the operator
asked for: Worked / Confirmed / QSL sent / To be sent, and inside each, which
channels count — paper QSL, LoTW, eQSL, QRZ.com. No ticks means every channel,
because a rule the operator has not narrowed must not quietly become a rule
about nothing.

"To be sent" is FIRST in the order, and that is the substantive decision here.
A contact can be confirmed on LoTW and still owe a paper card; the colour an
operator scans for is the one meaning "something is still owed". Placed after
"confirmed" that row goes green and the card never gets printed.

"Worked" is the catch-all — nothing sent, nothing requested, nothing back — and
is off by default, since turning it on paints every remaining row.

R and Q both count as owed: ADIF says requested and queued, and both mean the
card has not gone out.
