Get a presigned S3 URL to upload the modification's supporting document
POST/api/v1/cart/:cartId/modification/upload-url
Upload the file bytes to uploadUrl with a PUT and the same Content-Type, then send the returned objectUrl as attachmentUrl when requesting the modification. Accepts image/* and application/pdf. The object is private — read it back through the attachment URL endpoint, not the stored URL.
