Content: publish/hide chapters, sections and articles

- migration V5 adds published flag (default true) to chapters/sections/articles - ContentService: tree(includeHidden) filters, treeAll(), findArticle(includeHidden), set*Published; public tree/article expose only published items - admin API: GET /tree/all, GET /all/{chapter}/{section}/{article}, PUT /{chapters|sections|articles}/{id}/published - web: learn pages for admins load the full tree, show "скрыто" badges and publish/hide buttons for every chapter, section and article; hidden articles open in preview for admins, guests get "not found"; article view carries published flag
