Missing UI error handling for "same password" policy requirement

[natalian98]

If a user tries to reset their password to the same one they already have, the UI doesn't show any error message, even though the server responds with a 500 and status message "new password does not meet the password policy requirements: The new password must be different from the old password."

Steps to reproduce:

1. Log in with the test@example.com user.
2. Go to password reset page, set the password to test and submit the form.
3. Login UI backend responds with an error but it is not displayed in the UI.
