Note:

This is a small backend fix focused on email update behavior in the user profile controller. Please verify API response consistency and validation behavior during review.

Important: After changing your email address, you may encounter a "User Not Found" error if you continue using the old email, as it will no longer exist in the database. Please log out and log in again using the updated email address.
