fix(e2e): migrate E2E namespace from privilegedescalation-dev to headlamp-dev

The E2E workflow and deploy scripts were targeting the legacy
privilegedescalation-dev namespace, which is not managed by Flux GitOps
in privilegedescalation/infra.

The infra repo (PR #11) already provisions the headlamp-dev namespace
and corresponding RBAC (e2e-ci-runner-headlamp-rbac.yaml) that grants
the ARC runner SA (runners-privilegedescalation-gha-rs-no-permission in
arc-runners) the permissions needed to deploy/teardown the E2E
Headlamp instance.

This change aligns all E2E infrastructure to use headlamp-dev:
- .github/workflows/e2e.yaml: E2E_NAMESPACE=headlamp-dev
- scripts/deploy-e2e-headlamp.sh: default namespace and comments
- scripts/teardown-e2e-headlamp.sh: default namespace
- deployment/e2e-ci-runner-rbac.yaml: namespace and add missing events
  permission (already present in infra copy)
