fix(perry-ui-gtk4): webview.rs follow-up — TimeSpan + mut action (v0.5.865)

v0.5.864 left 2 more errors in webview.rs surfaced once the build was
re-enabled:

1. `WebsiteDataManager::clear` takes `glib::TimeSpan`, not
   `std::time::Duration`. Use `TimeSpan::from_seconds(0)` for "from
   epoch" semantics.
2. `action_decision.navigation_action()` returns a wrapper that needs
   `&mut self` for `.request()`. Bind as `mut`.
