[App] Background Reference for Product to Model

You can now use a Background Reference image in Product to Model to anchor your generations to a specific location or setting.

The provided image is used as the backdrop, ensuring consistent environments across campaigns. If a person appears in the reference image, they will be ignored — only the background is used.

Generated models now interact naturally with the scene, adapting to lighting, perspective, and physical elements like ledges or furniture to produce realistic, integrated compositions.
