What changed in this PR

Adds ACL-agent VM images to the parallel Tailor image workspace as part 12 of the migration stack, supporting agent-driven A/B update testing.

Changes:

  • Adds amd64 ACL-agent base (qcow2) and update (cosi) scenarios using shared UKI usr-verity configuration.
  • Defines persistent partitions for agent state, kubeconfig, and Trident configuration across A/B updates.
  • Adds agent service overrides, test-CA installation, and documentation of service enablement.
