Improve webview destruction to avoid rare screen lock

Description of this change

Improve the WebView component handling during the dialog dismissal flow, preventing occasional crashes and screen lock.

1. Improved cleanup process for WebViews
2. Workaround for the "[ERROR:aw_browser_terminator.cc(154)] Renderer process crash" issue by:
   • Disabling JavaScript execution during cleanup and removing event listeners
   • Adding delays to allow WebView internals to execute properly
3. README improvements to make the local development easier.
