refactor: use isEmpty() instead of size() > 0 for better readability and performance

[devin-ai-integration]

Summary

Replaces userRepresentations.size() > 0 with !userRepresentations.isEmpty() in the createUser method of UserServiceImpl.java.

This change improves code readability by using the idiomatic Java approach for checking if a collection has elements. Additionally, isEmpty() is guaranteed O(1) whereas size() can be O(n) for some collection implementations.

Review & Testing Checklist for Human

• Verify the logic is semantically equivalent (both check if the list has any elements)
