fix: use headlamp-plugins-e2e namespace for E2E tests, revert workflow

headlamp-dev is Flux-managed (kustomization/headlamp-dev reconciles), causing
E2E deployment conflicts and test failures. Use a dedicated headlamp-plugins-e2e
namespace instead. Reverted .github/workflows/e2e.yaml — Hugh owns CI/CD; will
file a child issue to update the workflow namespace.
