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

[vigneshrajsb]

Problem

When a service config specifies a custom helm.chart.repoUrl (e.g., an OCI ECR registry), the generated helm upgrade command was ignoring it for services that use the org chart (goodrx-app). The command would use just the bare chart name with no repo reference:

helm upgrade --install lifecycle-docs-<uuid> goodrx-app --namespace ... --version 2.2.1 ...

Root Cause

determineChartType returns ChartType.ORG_CHART when chartName === orgChartName && helm.docker is set. In constructHelmCommand, the else branch (which handles ORG_CHART) unconditionally used the bare chartPath and never checked chartRepoUrl:

} else {
  command += ` ${chartPath}`;  // always "goodrx-app", repoUrl ignored
}

The generateHelmInstallScript function also only ran helm repo add for ChartType.PUBLIC, skipping ORG_CHART entirely.

Note: mergeChartConfig correctly gives service-level repoUrl priority over global config — the value was properly resolved, just never used.

Fix

constructHelmCommand — add OCI detection to the ORG_CHART branch:

} else {
  const isOciChart = chartRepoUrl?.startsWith('oci://');
  if (isOciChart) {
    command += ` ${chartRepoUrl}`;
  } else {
    command += ` ${chartPath}`;
  }
}

generateHelmInstallScript — extend helm repo add to also cover ORG_CHART with a non-OCI custom repoUrl:

if (chartType === ChartType.PUBLIC || chartType === ChartType.ORG_CHART) {

After this fix, the generated command correctly uses the OCI URL as the chart reference:

helm upgrade --install lifecycle-docs-<uuid> oci://441168312025.dkr.ecr.us-west-2.amazonaws.com/goodrx-app --namespace ... --version 2.2.1 ...
