Fix user login after registration

[emilvn]

Description

Users reported that they would like to be logged in automatically after they register, instead of being redirected to the login page and asked to log in again. This pull request fixes this issue by modifying the behavior of the registration process. After successful registration, the user will now be automatically logged in. The changes include updates to the App.tsx and Register.tsx files.
