Refactor: Remove inline `get_admin_namespace` function from `enhanced_auth_middleware.py`

- Eliminated the inline `get_admin_namespace` function to streamline the code and improve readability.
- The function is now imported from the centralized `config.middleware` module, enhancing code organization and reusability.
