File picker previously embedded base64 image data in the image_data widget, bloating workflow JSON past the 5MiB localStorage limit (Failed to save workflow draft). Now uploads via POST /upload/image with type=temp and stores a small '<path> [temp]' reference; backend resolves it with get_annotated_filepath. Base64 data URLs from older saves still load via backward-compat path.
