RHDH Helm and Operator smoke tests

Smoke test after an RC (Quay CI chart / IIB). Catalog-index OCI refs run first. Helm and Operator are both mandatory after that. One Helm namespace and one Operator namespace — the three checks are a chain in that namespace, not three installs.

This is not full QE, Prow e2e, local compose, or an operator-PR catalog test.
