DROID-93 Add Device name to Create account flow

We want to show the device name in more places so that users see it as early as possible. Therefore we should also present the device name when a user creates an account through the app. This is done by showing the device name underneath the new account number and also includes an info button that opens a dialog explaining the device concept further.

Note: The Confluence and Zeplin links references other work as well

So this is more future-proofing, but we will add other types of dialoges in this view in the future connected to billing.
How do you envision that would work so that they do not conflict?

I think later on when we introduce navigation in compose we should have them as navigational paths. Much like you navigate to a screen (or fragment in our case) we should navigate to a dialog.
