ci: ajout du deploiement continu avec gitea actions

- Backend IA :
  - Intégration d'OpenCV (WebAssembly) pour la détection et certification des cibles (anneaux concentriques, confiance).
  - Ajout du système de journalisation complet des uploads (SQLite, IP, appareil, statut, métadonnées).
  - Implémentation du système de modération (bannissement/débannissement de wallets, rejet 403 avec motifs).
  - Harmonisation des codes d'erreur et messages JSON (UPLOAD_SUCCESS, WALLET_BANNED, etc.).
  - Dashboard Next.js : page dédiée aux logs avec filtres, export CSV et actions de modération en un clic.
- Application Mobile (Flutter) :
  - Encapsulation des réponses d'export dans AiExportResult avec gestion fine des erreurs et statuts.
  - Mise à jour du disclaimer de participation à l'entraînement IA avec avertissements stricts de bannissement.
  - Révocation de l'envoi de photos et affichage d'un bandeau explicatif en cas de suspension.
  - Ajout d'un bouton manuel « Actualiser mon statut » dans les paramètres pour synchroniser l'état du compte.
  - Possibilité de configurer l'URL/IP du serveur IA directement depuis les paramètres.
