Implement Configuration Import via URL for MacOs

[AlinaNaletova]

Issue Details

Develop a feature to import settings via a custom URL scheme, aimed at streamlining the configuration process for users and enhancing cross-platform compatibility.

Proposed solution

Functionality:

• URLs can be generated post-issue creation on GitHub or via the 'Share settings' option in the app's context menu.
• The URL format is adguard:import_user_configuration and will include parameters specified by the user.
• Clicking on "Import settings" triggers a confirmation dialog. If confirmed, the settings are applied and a success notification is displayed.
• Only settings from the user's report are included in the URL.
  This feature is crucial for filter developers and end-users, facilitating easier setup and enhanced interoperability across different platforms.
