[fix] Add missing deployment-info artifact creation in playwright workflows

- Capture wrangler deployment URL output and save to GitHub outputs
- Create deployment-info artifacts with test results and deployment URLs
- Add test exit code tracking in test-ui.yaml workflow
- Add PR number logging for debugging
- Improve URL extraction with multiple patterns and fallback

This fixes the issue where PR comments were missing deployment links because the deployment-info artifacts were never created.
