Articles created via Micropub were always published immediately,
ignoring the client-supplied post-status property. Clients like iA
Writer that publish drafts (post-status: draft) had no way to land
an article as unpublished.
EntryData now extracts post-status from the request, and
ArticleService sets published accordingly, defaulting to true when
the property is omitted or set to anything other than "draft".
