Captions in photo bursts and media group albums were silently dropped when a shorter caption happened to be a substring of an existing one (e.g. "Meeting" lost inside "Meeting agenda"). Extract a shared _merge_caption static helper that splits on "\n\n" and uses exact match with whitespace normalisation, then use it in both _enqueue_photo_event and _queue_media_group_event. Adds 13 unit tests covering the fixed bug scenarios. Cherry-picked from PR #2671 by Dilee.
