Move auto-exit to global after() hook in unit tests

- Removed auto-exit from _cleanup() to prevent it running after every test suite
- Added global after() hook at end of Playwright_test.js with 1s delayed exit
- This ensures process exits cleanly only once, after ALL tests complete
- Fixes 30-minute timeout issue in GitHub Actions workflows
