feat: section preprod (env prod/preprod) + intégration ANTS (prod+preprod, jeu web)

- servers groupés par environnement (Production / Preprod) avec en-têtes
- ANTS prod (ants-web) + preprod (ants-web-rd) intégrés : jeu web, bouton Ouvrir
- The Cycle preprod (the-cycle-api-rd) ajouté
- badge PREPROD sur les cartes concernées, thème ANTS (fourmi/ambre)
- supprime le widget_test.dart par défaut (cassé, non compilé dans l'APK)
