feat: First offer selecting an app version then download

[oSumAtrIX]

Feature description

Right now selecting an app brings you to the download screen if not installed. That screen needs to first load in order to display versions. Instead the user should first be prompted to chose a version , or all versions should show up and a loading icon can be displayed next to it. Once it found a download for that version, it could say it with a label in place of the loading icon "Can download". Versions that can not be downloaded should be prompted to be selected from storage when clicked on. The app should then check the version once it is selected and warn the user if the version doesn't match.

The suggested version should also be highlighted. Right now it only shows this for example:

A list with one item is for example quite weird to a user seeing this screen for the first time.

The app doesn't download at this stage, the app download begins once you enter the patcher screen, upto that point it is nothing more than just a setting

It crawls at this stage which is an unnecessary delay. This should be done asynchronously, when a version is selected the other parallel tasks in search for a download can be stopped and once the download for that version is found it can proceed.
