feat: add blockMedia, returnOnlyCookies, PDF handling and fix timeout/networkidle

- Catch both builtins.TimeoutError and playwright TimeoutError as 408

- Check challenge title before networkidle to avoid timeout on Cloudflare interstitial

- Add blockMedia and returnOnlyCookies request options

- Return raw PDF bytes as base64 with contentType application/pdf

- Skip tests on 408 timeouts; add PDF handling test
