This commit introduces a new component `AuthRedirect` which checks
if a user is already logged in.
If the user is logged in and attempts to access the /login or /register
pages, they will be redirected to the /console page. Otherwise, the
respective authentication form (Login or Register) will be rendered.
The `App.js` file has been updated to utilize this new `AuthRedirect`
component for the /login and /register routes.
