Frontend: Editorial-Relaunch der öffentlichen Strecke + Ausgaben-Routing

Öffentliche Seiten auf gemeinsames Editorial-Design (x-web.site-header/-footer,
Design-Tokens) und Ausgaben-Präfix /{edition}/ (de|en) umgestellt.

- Routing: neue Middleware SetEdition (Locale + URL::defaults), /{edition}-Gruppe
  in routes/web.php, Root-Redirect auf /de, 301 für Legacy-.html-URLs,
  Baseline-Default in AppServiceProvider.
- Neue URL-Schemata: /{edition}/press-release/{slug}, /{edition}/category/{slug}.
- Ausgabe = Sprache: DE/EN-Umschalter (Region/CH/AT entfernt); EditorialClock
  und Livewire-Komponenten sprachdynamisch.
- Detail-, Kategorie- und Veröffentlichen-Seite mit echten Daten neu aufgebaut.
- Suche aktiviert: Volt-Komponente livewire/web/search (Titel/Text/Keywords +
  Firma + Rubrik, Filter, Sortierung, Pagination, URL-Parameter q/category/sort).
- Rubriken-Navigation statt Übersichtsseite: Helper CategoryNavigation;
  web/kategorien.blade.php + Route entfernt (Legacy-301).
- Tests: Edition-Routing, Kategorie-Seite/-Navigation, Detail, Veröffentlichen,
  Suche, EditorialClock. Doku in "Echte öffentliche Unterseiten.md" aktualisiert.
