Fixes a regression where get_siblings() built invalid SQL (ORDER BY id ASC AND id != %d) whenever an exclude ID was passed. This silently broke the sibling-propagation step of OTP verification for multi-file entitlement groups — a customer verifying via one file's link would get that file granted, but any sibling file(s) on the same order item were left stuck pending forever, with no error status and no cron retry.
One affected production row (order #1463) was identified and manually remediated; a full scan found no other affected rows.
