feat: Parse app info in the app info screen when selecting a downloadable app

Feature description

Right now the package name and a generic icon is shown:

I believe one the app was found online , it doesn't hurt to parse the metadata such as the icon or title for it.

When the app is an installed app, this can be done even before the app is found online. The app icon and title are already shown in the app selection screen.
