fix: skip the pending production check on update-after-submit saves

Saving a submitted manufacture entry to change an allowed field re-ran
the pending production cap with a manufactured aggregate that already
includes the entry itself, so the save was rejected against the
post-entry remainder. Quantities are not editable after submit, so the
check has nothing to protect there.
