[UI] Add Wallet - remove oobe backgroud

[soosr]

Closes #12715

This PR only removed the BG when adding a wallet. For welcome screens (and for the first wallet) it still be there as it has two purposes:

• The wallet list is empty, there is nothing to show in the background, and it looks odd.
• Make the initial experience more engaging and memorable for first-time users.

TBH the wallet creation is a very crucial process, it made sense to hide the background completely with the OOBE background. After this PR the user's attention is not 100% forced on the dialog.

This is my feedback, if the majority still insist on removing the BG, then go with it.

If the reason is to keep the users attention on the dialog, then it makes more sense to remove the OOBE for the welcome screens since the wallet list is empty as you stated above, so there is nothing that should take the user's attention.

My suggestion is to blurry out the background more and remove OOBE completely.

You didn't understand the point. It is totally empty. Even the the main screen navigation stack is empty. It just looks shit.

so there is nothing that should take the user's attention.

Obviously the empty background is more distracting than the OOBE bg.

My suggestion is to blurry out the background more and remove OOBE completely.

NACK, bad idea with more complexity for almost zero benefit.

Really? OOBE now has these moving elements (circles and shapes with different colors) which is definitely more distracting than an empty background.

If there is no benefit to blurry out the background or to make the window smaller to only show the dialog (as suggested by Dan) then there is no user distraction as claimed, and thus no need to use OOBE in the first place.

For the complexity argument you and I both know that there are far more unnecessary complexities all over the UI, for example the welcome screens themselves.

How about a solid dark color as OOBE background?

This starting to smell like Minefield.
