fix(e2e): serialize concurrent E2E runs to prevent environment conflicts

Concurrent E2E runs share the same headlamp-e2e release name in privilegedescalation-dev. When two runs overlap, one run's teardown (if: always()) deletes the shared Deployment/Service/ConfigMap while the other is still using it, causing Playwright auth setup to time out waiting for the Headlamp UI. Adds a repo-wide concurrency group so only one E2E run executes at a time. cancel-in-progress: false queues incoming runs rather than cancelling in-flight ones to avoid leaving dangling cluster resources when teardown is interrupted.
