Research direction

Start at the /file-upload endpoint and trace how uploaded images are processed when the client requests a preview. Reproduce the failure with the reported IMG_4408.HEIC example and use the server log's unsupported-codec error to identify the handling path. Done means supported uploaded pictures produce a preview instead of a Retry button.
