TOT-12 Account Deletion and fixing login/logout issues (with JWT)

Using this, we can enable the user to remove their identifying information. We have added authentication and authorization. We resolved issues concerning the handling of login on the client/server with the JWT token, and improved error messaging for a better user understanding what is happening.

Test Case	Expected Result
Login with incorrect information	Receive an error message
Login with a deleted user	Receive an error message. After refresh, the user should still be logged out
Delete user info with correct password	Successful deletion
Delete user info with incorrect password	Receive an error message
Logout	User stays logged out even after a page refresh
