Create a comment or reply on a post
content and/or media (at least one resolved media item or non-empty text required). The media array matches post threads: each entry is an integer library id (from POST /api/v1/media/upload/file or POST /api/v1/media/upload/url) and/or an HTTPS URL to import (direct image/video, supported social post URLs, Unsplash—same as the media library URL flow). If you send only media and none of the entries resolve, the request returns 422. For a reply, set parent_comment_id; post_id must still refer to the same post as the parent (validated server-side).
