Extract the MIME validation, file storage and project reload from the v1 UploadBackground handler into ValidateAndSaveBackgroundUpload so the upcoming v2 handler can reuse it instead of duplicating the logic. The v1 handler keeps its exact wire behaviour; the inline "not an image" check now returns a typed ErrFileIsNoImage that the handler maps to the same message.
