fix(jeu): overlay fonctionnel — CSS complet + URL sanitizée + data-state

- jeu.php : supprime les espaces de l'URL (preg_replace), ajoute data-state="initial" sur l'overlay
- Article.svelte : porte le CSS complet depuis l'ancienne app React
  (background opaque, play icon, hover, deactivate btn, game-active state)
- JS : ignore les clics sur overlay ended, remet data-state="initial" au deactivate
