fix(pri-1127): update default E2E namespace to headlamp-dev

Updates the default E2E_NAMESPACE from privilegedescalation-dev to
headlamp-dev to match the actual namespace used by the reusable E2E workflow.

Also updates comments and RBAC path references to reflect the new
infra repo structure (apps/base/e2e-ci-runner-rbac.yaml).

Fixes PRI-1127
