Modify the cleanup function to remove all userdata keys created during the test, instead of just deleting a single predefined key. This ensures a more thorough cleanup of temporary resources. Move the KEY_PATH variable definition inside the set_user_data function to reduce global variables and improve encapsulation. The KEY_PATH variable is now dynamically created when setting user data. This change has no effect on the current test, while improving an upcoming test that would create several userdata entries.
