The renderScene function was passing local data URLs (data:image/png;base64,...)
as imageUrl and referenceUrls to createVideoTask, which the /api/ai/video endpoint
rejects with 400 Bad Request. The planning phase already uploads images to OSS
but the resulting URLs were not returned to the component.
- Add imageUrls field to EcommerceVideoPlanResult
- Return OSS imageUrls from runVideoPlan alongside existing plan data
- Use planResult.imageUrls[0] in handleRender instead of productImageDataUrls[0]
- Use planResult?.imageUrls[0] for sourceImage display fallback

runVideoPlan was passing blob URLs as "dataUrl" to uploadAssetWithProgress,
which sent them to /api/oss/upload (base64 path). Blob URLs don't match
DATA_URL_PATTERN regex, causing corrupt 44-byte files on OSS.
Now uses uploadAssetBinary (FormData multipart) via /api/oss/upload-binary,
fetching blob → uploading binary directly, same as EcommercePage path.
