Automatic proxy configuration

Description

I am required to use automatic proxy configuration. When I install the Proxy Helper tool and the application starts, it overrides the current system proxy settings as expected. However, when I stop the application, it does not fully revert the changes, leaving the automatic proxy configuration on but with an empty URL.

Steps to Reproduce

1. Enable Automatic proxy configuration in the settings.
2. Install Proxy Helper tool
3. Run the app
4. Check the Automatic proxy configuration is disabled.
5. Stop the app
6. Check the Automatic proxy configuration is enabled, but URL is empty.

Current Behavior

Automatic proxy configuration is empty when stopping the app.

Expected Behavior

Automatic proxy configuration is restored to the previous state with provided URL.

Environment

• App version: e.g Proxyman 5.3.0
• macOS version: Sequoia 15.0.1
