feat(ui): airdrop login and code sharing on setup screen

[peps]

This adds a new element to the Setup Screen that allows users to log in and share their referral code while they wait for the App Setup process to complete.

@PanchoBubble I moved the Airdrop login functionality to its own hook useAirdropAuth which exports handleAuth and checkAuth.

I also disabled the isFirstLoad check on the AirdropPermission component. I now have it hooked up so if the user disabled telemetry the new Share/Login UI will toggle. This makes it pretty obvious that telemetry is required in order to collect gems.

Since this changes the code that handles the login functionality and auth checks, we should test the login functionality both on the setup screen and the sidebar.

@peps Sorry mate. I was about to merge this and now it's conflicted.

No worries :) Looking into it now

@brianp it should be ok now. This PR involves moving the Airdrop Login logic into a separate hook useAirdropAuth so any change to the inline logic there will be a conflict.

I tested pretty thoroughly myself, but when testing make sure to test both...

1. The login functionality on the Setup screen
2. The login functionality in the Sidebar

They're both sharing the same useAirdropAuth hook to handle the login flow.

LGTM! just the new conflicts (sorry!)
i like this setup screen app version a lot better:D

btw, not sure when #1335 will go in, but it will likely cause even more conflicts, so not sure if you want to wait for that, or resolve here and i can resolve there after this is merged?
