fix: save_state captures cross-domain cookies and localStorage (#1064)

The Rust rewrite of save_state only captured cookies and localStorage
for the current page's origin, silently dropping cross-domain data
(e.g. SSO/CAS auth cookies). This was a regression from the JS version.

Cookies: replace Network.getCookies with Network.getAllCookies to
return cookies from all domains the browser has visited.

localStorage: track visited origins in BrowserManager during navigation,
then collect their localStorage via a temporary CDP target with Fetch
interception (serves blank HTML to avoid real network requests).
