Fix Doctrine ORM deprecation warnings by using native lazy objects on PHP 8.4+

- Use Configuration::enableNativeLazyObjects(true) on PHP 8.4+ with Doctrine ORM 3.4+
- Fall back to traditional proxy configuration (setProxyNamespace/setProxyDir/setAutoGenerateProxyClasses) for older PHP versions
- Resolves deprecation warnings about setProxyNamespace and setAutoGenerateProxyClasses
- Maintains full backward compatibility with older PHP/Doctrine versions
