feat(hamlog): send to HAMLOG.online from the right-click menu

The upload targets in the QSO context menu gain HAMLOG.online, so a selection
goes there the same way it goes to QRZ or LoTW.

The confirmation toast now names the service from a map rather than a chain of
ternaries that stopped after three: hrdlog, eqsl and hamlog were echoed as their
internal ids, which is not what the operator clicked on.
