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)

-### Etap: Banners, Menu, Pages, Articles, Layouts Frontend Services
+### Etap: Articles Frontend — ZREALIZOWANY
+
+**Cel:** Migracja `front\factory\Articles`, `front\view\Articles` i statycznych metod `class.Article` do Domain + Views.
+
+**DODANE METODY (do istniejącej klasy `ArticleRepository`):**
+- `articleDetailsFrontend(int $articleId, string $langId): ?array` — z copy_from fallback + Redis cache
+- `articlesIds(int $pageId, string $langId, int $limit, int $sortType, int $from): ?array` — złożone SQL z language fallback + sortowanie + LIMIT + Redis cache
+- `pageArticlesCount(int $pageId, string $langId): int` — COUNT z Redis cache
+- `pageArticles(array $page, string $langId, int $bs): array` — paginacja
+- `news(int $pageId, int $limit, string $langId): ?array` — inline sort_type query (eliminacja zależności od `front\factory\Pages`)
+- `articleNoindex(int $articleId, string $langId): bool` — jawny $langId zamiast `global $lang`
+- `topArticles(int $pageId, int $limit, string $langId): ?array` — ORDER BY views DESC + Redis cache
+- `newsListArticles(int $pageId, int $limit, string $langId): ?array` — ORDER BY date_add DESC + CacheHandler (Redis) zamiast legacy `\Cache`
+
+**NOWE:**
+- `front\Views\Articles` — czysty VIEW + utility:
+  - Renderowanie: `fullArticle()`, `miniatureArticlesList()`, `entryArticlesList()`, `fullArticlesList()`, `news()`, `newsList()`
+  - Utility: `generateTableOfContents()`, `processHeaders()`, `generateHeadersIds()`, `getImage()`
+
+**ZMIANA:**
+- `front\factory\Articles` → fasada (10 metod delegujących do repo + Views)
+- `front\view\Articles` → fasada (5 metod delegujących do repo + Views)
+- `class.Article` → USUNIĘTA (encja + metody statyczne przeniesione do `ArticleRepository` + `front\Views\Articles`)
+- `front\view\Site::show()` → 5 sekcji przepiętych na repo + Views
+- `front\controls\Site::route()` → single article + page_type switch przepięte na repo + Views
+- 5 szablonów `templates/articles/*` → `\front\Views\Articles::`
+- `tests/bootstrap.php` — dodany stub `S::is_array_fix()`
+- Testy: 13 nowych w `ArticleRepositoryTest` (450 OK, 1431 asercji)
