refactor: reorganizar estructura del proyecto al estándar app/api_config

- core/ → app/api_config/
- apps/backend_admin/ → app/backend_admin/
- apps/common/ → app/common/
- apps/promociones/ → app/promociones/
- manage.py → app/manage.py
- Añadir app/requirements.txt
- Actualizar todos los imports y referencias (DJANGO_SETTINGS_MODULE, ROOT_URLCONF, WSGI_APPLICATION, INSTALLED_APPS)
- Actualizar Dockerfile con nuevo WORKDIR
