refactor: Umstellung auf Mini-MVC-Architektur (Issue #46)

- Front Controller Pattern mit public/index.php als Einstiegspunkt
- Eigenes Routing (App\Core\Router) ohne externes Framework
- Controller: HomeController, ImpressumController, DatenschutzController
- Views mit gemeinsamem Layout (app/views/layouts/main.php)
- PSR-4 Autoloading
- Statische Assets nach public/ verschoben
- Alte Dateien (index.php, impressum.html, datenschutz.html) geloescht
- 301-Redirects fuer alte URLs
- PHP 8.5 kompatibel
- Apache DocumentRoot auf public/ gesetzt
