Implement a Global Handler for UserNotFoundException

Overview

This implementation enhances the exception handling mechanism within the Journal REST API application by defining a custom exception, UserNotFoundException, and implementing a global exception handler to manage this exception effectively. The goal is to centralize exception handling, improving code maintainability and consistency.
