chore: release v0.21.6

"Upload" was wrong for half of them: a paper QSL is not uploaded. Every entry
now says whether it sets a STATUS or a DATE, and in which direction — "QRZ.com
sent status", "LoTW received date" — which is also how the ADIF fields read.

Added: the QRZ.com received status (the column existed, it was simply never
offered) and the ten confirmation DATES — QSL / LoTW / eQSL / QRZ.com in both
directions, Club Log and HRDLog outbound only, those two having no return
channel. Dates use the same picker as the QSL Info tab, with a Today (UTC)
button; clearing the field writes an empty value, which is how a wrong date is
removed from a batch.

Fields are grouped by CHANNEL now, each status followed by its date, in the same
order as the QSL Info tab — a longer list, but nothing to hunt for.

The repository whitelist is extended to match: without it the new columns would
have been refused at write time. The old ids (qrz_upload, clublog_upload,
hrdlog_upload) still resolve, in case anything still holds one.
