Fixes to the account creation flow

The Google, X, and email connect methods showed errors the first time, the verification code email by root@auth0.com is considered spam and it doesn't look professional with "You’re receiving this email because you have an account in dev-yacn6ah0b1dc12yh" at the bottom; there should be some redirect to a user home or onboarding page if he's new and doesn't have coins to trade

From meeting chat:

"Get Tokens" flow (2nd step in the onboarding), at /deposit: the links to buy are old/broken and should be updated to the new hydration base URL; the addresses shown for the "Deposit from a Wallet or an Exchange" are different from the one shown at the top-right of the menu; there is no link to /deposit from the Buy/Sell panel of each prediction market (next to the disabled "insufficient ZTG" button); it might be worth to even add direct links (or even better an iframe or popup) to swap between"
