Replace singular reference_image field with reference_images list to support an arbitrary number of reference images. Map them to the correct BFL API parameter names based on model family: - flux-2-*: input_image, input_image_2, ..., input_image_8 - flux-kontext-*: input_image, input_image_2, ..., input_image_4 - flux 1.x: image_prompt (single) BREAKING CHANGE: reference_image config field renamed to reference_images (list).
