fix(e2e): grant cross-namespace RBAC for Polaris dashboard proxy access

The E2E Headlamp instance runs in privilegedescalation-dev but needs to proxy
to the Polaris dashboard service in the polaris namespace to fetch audit results.

Root cause:
- E2E tests consistently fail with 'Polaris dashboard not reachable' because
  the in-cluster Headlamp (running as ServiceAccount headlamp-e2e-test in
  privilegedescalation-dev) lacks permission to proxy to polaris-dashboard
  in the polaris namespace
- The default RBAC only covered the privilegedescalation-dev namespace
- The error manifests as a 503 from the Kubernetes API proxy, causing
  the loading spinner to persist indefinitely in E2E runs

Fix:
- Add a new Role + RoleBinding for the polaris namespace that grants
  get+proxy on the polaris-dashboard service
- The ARC runner's ServiceAccount (runners-privilegedescalation-gha-rs-no-permission
  in arc-runners) is the subject for both bindings, matching the existing pattern
- Add a pre-flight check in deploy-e2e-headlamp.sh that warns if Polaris
  proxy RBAC is missing, so CI output makes the issue self-diagnosing

Note: This RBAC change must be applied to the cluster before E2E runs will
pass. The deploy script detects and warns about the missing permission.
