update_story_media

act imperative

Update an attachment's editorial fields on a story: caption, alt text (required for publication) and the lead-image flag. Only sent fields are changed; a caption/alt-only update never touches the lead flag.

`altText`	string	no	Text alternative for screen readers; empty string clears it. Publication validation requires one per attachment.
