ver. 0.280: Articles frontend migration, class.Article removal, Settings facade cleanup

- Add 8 frontend methods to ArticleRepository (with Redis cache)
- Create front\Views\Articles (rendering + utility methods)
- Rewire front\view\Site::show() and front\controls\Site::route() to repo + Views
- Update 5 article templates to use \front\Views\Articles::
- Convert front\factory\Articles and front\view\Articles to facades
- Remove class.Article (entity + static methods migrated to repo + Views)
- Remove front\factory\Settings facade (already migrated)
- Fix: eliminate global $lang from articleNoindex(), inline page sort query
- Tests: 450 OK, 1431 assertions (+13 new)
