WinForms gets the same per-row button and dialog Chardonnay has, and its scan
picker lists an account's marketplaces for the same reason.
list-accounts grows an 'Also scans' column, because printing one locale for an
account that reads three misreports what a scan will do. It appears only when
some account has more than one marketplace, so the ordinary table is unchanged;
--bare always emits the field, last, so a script reading the first five keeps
working.
Compile-checked only for WinForms: it builds on Linux via EnableWindowsTargeting
but cannot run there, so the new dialog's layout still needs a look on Windows.
