Pull request overview

Adds a new default ordering for vulnerabilities that incorporates the (aggregated) earliest target remediation date, and propagates the new ordering field through MariaDB ordering/cursor logic plus tests/docs.

Changes:

• Introduce IssueEarliestTargetRemediationDate as a new OrderByField and add MariaDB column mapping for it.
• Extend issue query/cursor generation to support ordering (and cursor encoding) by earliest target remediation date.
• Update/extend tests and documentation to reflect the new default ordering behavior.
