Add WordPress as an enterprise-site CMS type alongside pbootcms, and let
schedule tasks auto-publish generated articles to enterprise sites.
- WordPress connection/publisher service and tests; register wordpress
media platform and relax cms_type CHECK constraint
- New publish_enterprise_site_targets JSONB column on schedule_tasks with
array type constraint; thread targets through scheduler dispatch,
prompt/KOL generation, and worker
- Admin UI: enterprise-site targets in generate/schedule/publish flows,
KOL package form, MediaView, and i18n strings
