fix(validation): Resolve PSA collisions in base integration tests

Apply the PSA cleanup and variable scope fixes to the base integration test playbook (`base-integration-test.yml`). This ensures GKE and other non-Slurm tests can also resolve static VPC names, clean up stale PSA connections pre-deployment, and correctly target them during failure recovery/rescue.
