Make Web apps installable on the home screen or desktop

Add a simple, opt-in setting that lets developers make an Objo Web application installable from supporting browsers. Users can add the application to their home screen or desktop and open it in its own app window with the developer's chosen name and icon.

Studio should generate the necessary installation metadata and icon sizes automatically, using the project's existing display name, application icon and Web appearance. The normal setup should require one switch, with a small preview and optional customisation for developers who need it. No manual JSON, JavaScript or extra server endpoints should be required.

The application will continue to run on its server and require a connection to it. This feature provides browser installation and presentation; offline operation, background push and app-store publishing are outside its scope. Installation remains subject to the user's browser and platform, with HTTPS required for production deployment.
