Replace wallet loading animation with CoinJoin related content

[molnard]

General Description

I am looking at this screen a lot. Even with Turbosync, this screen is one which gets the most attention - it is displayed right after the user pressed the button.

What we see now is interesting but it is not "selling" anything. We should grab the opportunity and advertise/educate users on how CoinJoin works and why it is good. The first step is to figure out the concept of the animation but the purpose of this issue is not that but to propose the change.

More or less Duplicate of #9751

We can do in Avalonia Lottie animations https://github.com/wieslawsoltes/Avalonia.Skia.Lottie

Changed the title to be more precise about what is the point here.

This issue and all of these #9076 #9751 #10959 are related to the wallet loading screen. I guess we should have only one issue for all of these.

I would not close either of them, because they are all different. Whenever we will get to a point to work on this, one will create an epic issue that will gather all of these and converge them (or close with wont fix) into one solution.
