Onboarding issues from the Brave Wallet panel

[bbondy]

Couple of UX problems:

1. When opening the panel and clicking Restore, it takes you to the restore screen but the Back button doesn't work. In this case we should hide the back button.

2. When clicking on Getting started, it takes you to the exact same thing on the full page. We should instead go to the 2nd page in that case so the user doesn't need to click Getting Started twice. This should also not have a back button in that case when coming from the panel.

This one needs more UX to avoid jumping over MetaMask and crypto wallets detection specific UI. We should either support all logic from first onboarding screen within the panel or change the panel design to be less similar to the first screen of onboarding.

Good catch, I think we should probably support the same flows in the panel in that case.

Using 1.37.105, confirmed panel shows as per brave/brave-core#12008 (comment).
Confirmed clicking on "Learn more" button directs user to brave://wallet/crypto/onboarding.
