feat(export): right-click export can keep the OpsLog fields

The right-click export always called ExportADIFSelected with
includeAppFields=false, so it wrote strictly standard ADIF. That is the
right default when the file is going to another logger, but it silently
drops every APP_ tag -- and an award reference such as RDA@KR-04 lives in
APP_OPSLOG_AWARDREFS and nowhere else. Backing up a selection, or moving
it to another OpsLog, lost the awards.

Adds a second entry rather than a flag on the first: the two exports
answer different questions, and a checkbox in a context menu would have
to be read before every export.
