chore(infra): add url test to playwright (#11795)

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **Chores**
  - Updated Playwright test configurations to use full URL strings instead of port numbers for web server identification.
  - Unified server startup approach in test environments by integrating web server configuration directly into Playwright, replacing custom setup scripts.
  - Removed obsolete development server setup files to streamline test initialization.
