2. Login with KYC'd uphold account

Test Case 1

Disconnect from rewards using Disconnect from Brave Rewards using either the rewards panel or brave://rewards and ensure that clicking on Disconnected button reconnects your wallet and doesn't display any login flow as per #11528 (comment)

Test Case 2

Disconnect from rewards by removing Brave Browser from the Authorized Applications under Uphold which should disconnect the wallet from Brave. Go into brave://rewards and ensure that clicking on the Disconnect button reconnects your wallet and doesn't display any login flow as per #11528 (comment)

The above cases are not working for the rewards panel as the flow wasn't removed. Created #11760 .
