refactor(app): reduce tech debt by eliminating wry fork

[AlexTMjugador]

Overview

We currently maintain our own fork of wry with three significant changes:

• A change for injecting initialization scripts in every frame of the ads webview, which can now be achieved using the standard WebviewWindowBuilder#initialization_script_for_all_frames method.
• A change for ensuring that the ads webview remains muted on Windows platforms, which can be replaced by obtaining the native platform webview object via Tauri's Webview#with_webview method and calling the corresponding native API.
• A change for blocking popup windows from opening, which can be replaced by the standard WebviewBuilder#on_new_window method.

Since all these changes can now be implemented using standard APIs that don't require forking, and our wry fork is no longer being used in the latest release version (someone updated our Cargo.lock to use a newer upstream version, causing a build warning about the unused patch), this PR implements these changes using the discussed standard APIs, eliminating the maintenance burden of keeping our fork up to date, and preventing such patching failures from going unnoticed in the future.
