fix(nativeHelm): support OCI repoUrl override for ORG_CHART deploys

constructHelmCommand now detects OCI URLs in the ORG_CHART branch and
uses the full chartRepoUrl as the chart reference instead of the bare
chart name. generateHelmInstallScript extended to run helm repo add for
ORG_CHART when a non-OCI custom repoUrl is present, matching the
existing PUBLIC chart behavior.
