Implement Web Page for Sharing and Importing Configuration Settings

[AlinaNaletova]

Issue Details

Develop a web page that integrates with Adguard applications on macOS, allowing users to share their settings via a link or QR code.

Proposed solution

• From the context menu in macOS users can access a 'Share settings' button that opens the web page.
• The web page will feature a button to share with the link with settings (and possibly a QR code). Also there is a description about settings that will be imported.
• On this web page also there is a promotional block that can prompt installation of the Adguard application if not already installed.
• The 'Import settings' button on the page will use the custom URL scheme to open the respective Adguard application, prompting a confirmation dialog for importing settings.

This feature aims to enhance user engagement by simplifying the sharing of configurations and promoting the use of Adguard across different platforms.
