Display New UI by default

[bdresser]

Once #3386 is completed, we should put all users in the New UI by default.

• For users who were still on the old UI, we should display a welcome screen in the New UI. We can re-use the screen in Old UI component to suggest Beta UI #4811 with some updated copy
• The option to switch to "Old UI" should remain in settings (for now)
• Old UI should include a persistent banner that asks the user why they prefer the old UI. @bdresser to find appropriate survey / feedback mechanism.

Until this is implemented, is there a way to fetch whether the user is on the old or new UI?

@CruzMolina I don't think you can detect which UI they're on, but you can check their version with

web3.version.getNode(function(err, result){ console.log(result) })

@bdresser Gotcha 👍

Any ETA on when this will be implemented? By Nov 2nd's privacy update or prior to?

@CruzMolina We'll be on the new UI well before 11/2, hopefully in the next couple weeks
