Investigate xqueue CI failure in run_ci (ubuntu-latest, 3.11)

[Copilot]

Description

The failing run_ci (ubuntu-latest, 3.11, xqueue) job was traced to an import failure inside the mounted xqueue service code, not to a breakage in edx/devstack itself. The crash occurs during Django URL loading with ModuleNotFoundError for django.views.decorators.csrf.

• Root cause identified

  • CI job 91987318527 fails in xqueue startup path:
    • submission_queue/views.py imports csrf_exempt
    • runtime raises ModuleNotFoundError: No module named 'django.views.decorators.csrf'
  • Stack trace points to /edx/app/xqueue/xqueue/... (workspace-mounted xqueue repo code).

• Repository impact

  • No in-repo devstack code path was found that can directly patch this import failure.
  • Failure is attributable to upstream xqueue checkout/version compatibility in CI.

# failing import in xqueue service code (outside this repo)
from django.views.decorators.csrf import csrf_exempt
