Remove custom domain testing from workflows

- Remove all custom domain SSL testing and health checks
- Use only canonical Knative domains for all testing
- Update all workflows to use domain secrets for health checks
- Remove kubectl dependencies from deployment workflows
- Update index.html to v2.0.2 for testing canonical domain workflow
- Simplify smoke tests to focus on Knative canonical domains only
- Clean up auto-promotion summaries to remove SSL references

All workflows now test only the canonical Knative domains and avoid
custom domain complexity for a cleaner, more reliable pipeline.
