feat(jenkins): enhance E2E testing and debugging capabilities

- Updated Jenkinsfile to include Playwright's trace option for better debugging on test failures.
- Added archiving of test results, including trace files, error context, and screenshots for failed tests.
- Enhanced error handling in `auth.setup.ts` to log diagnostic information when authentication fails, improving visibility into issues.

These changes aim to improve the reliability and debuggability of E2E tests.
