Fix: Carga de recursos en macOS Bundle + limpieza Makefile

- Arreglar getExecutableDirectory() para usar _NSGetExecutablePath en macOS
- Añadir getResourcesDirectory() con soporte MACOS_BUNDLE
- Actualizar main.cpp y engine.cpp para buscar recursos correctamente
- Eliminar referencias obsoletas a directorio 'config' en Makefile

Ahora resources.pack se busca en ../Resources/ cuando MACOS_BUNDLE está
definido, permitiendo que la app bundle funcione correctamente.
