Postiz's /public/v1/posts expects a nested envelope:
{ type, date, shortLink, tags, posts: [{ integration:{id}, value:[{content}], settings:{__type} }] }
The earlier shim's flat {content, integrationIds, type, scheduledAt} was
rejected with "All posts must have an integration id" (the field is named
integration, not integrationIds; it's a nested object, not an array of strings).
Also: Postiz treats PostItem.value[] as thread segments, so createThread now
sends ONE request with multiple value entries rather than N grouped posts.
Callers now pass full {id, identifier} tuples so settings.__type is set
correctly (otherwise Postiz can't route to the provider handler).
