How to test changes / Special notes to the reviewer:
To verify the Local Admin UI test locally:

1. Ensure you are logged into an active OpenShift cluster via your terminal (oc login...).
2. Run the bash wrapper:
   ./run-ui-tests.sh tests/admin-login.spec.ts --project=chromium --headed
3. The script will automatically use the CLI to fetch the GitOps cluster URLs and Admin password, bypass the SSO login, and run the Playwright test against the local admin dashboard.
