- Add 6 frontend methods to LayoutsRepository (Redis cache, 3-level fallback)
- Add 6 frontend methods to PagesRepository (Redis cache, recursive pages)
- Create front\Views\Menu (clean VIEW replacing front\view\Menu)
- Delete front\factory\Layouts, Menu, Pages + front\view\Menu + dead submenu.php
- Fix null $lang_id TypeError in check_url_params() (remove string type hint + ?? '')
- Optimize Helpers::htacces() from 3 layout calls to 1
- Tests: 470 OK, 1484 assertions (+16 new)
