test: improve Playwright test reliability with timeouts and race condition fixes

- Fix race condition in subdomain creation test using Promise.all
- Add 15-second timeouts to element visibility checks across domain tests
- Add timeouts to tab clicks and count verification functions
- Prevent flaky test failures in CI/CD environments
