fix: guard all browser subresources against SSRF and fail closed

Browse Source 
The CDP Fetch interceptor only paused main-frame Document requests, so a
scraped page's <img>/fetch()/XHR subresources to internal targets
(169.254.169.254, postgres:5432, RFC1918) reached those hosts unguarded.
Drop the ResourceType::Document constraint so every request runs through
is_blocked. Also make open_page fail-closed: if the guard can't install,
close the blank page and return the error instead of navigating unguarded.
