docs(ai-export): state what the training upload sends and drop the anonymity claim

- 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.

 # Changelog
 
+## [v1.0.3] - 2026-08-27 (Branche `design/newdefault`)
+
+### 🎨 Refonte UI/UX "Tactical & Precision"
+- **Système de Thèmes & Couleurs d'Accentuation Personnalisables** : Choix dynamique de la couleur d'accent dans les Paramètres parmi 7 déclinaisons tactiques (Bleu Cobalt, Rouge Cible, Vert Viseur, Orange Ambre, Violet Cyber, Cyan Néon, Or Compétition) avec persistance SharedPreferences.
+- **Nouvelle Direction Artistique & Thèmes** : Thème sombre Gunmetal/Slate contrasté pour stand de tir et thème clair technique épuré avec effets Glassmorphism et flous d'arrière-plan.
+- **Barre de Navigation Principale** : Intégration de la `NavigationBar` Material 3 avec indicateur pill moderne et icônes thématiques.
+- **Dashboard d'Accueil** : En-tête dynamique "BULLY • PRÉCISION", carte interactive de session en cours (badge lumineux, reprise rapide / fin sécurisée), tuiles télémétriques de KPIs avec graphique d'évolution et accès direct aux dernières séances.
+- **Armurerie (Arsenal)** : Fiches d'armes techniques avec mise en valeur du calibre, compteurs de chargeurs/coups, puces d'accessoires et **icônes vectorielles dédiées pour chaque type d'arme** (Arme de Poing, Arme d'Épaule, Fusil à Pompe, Airsoft/Airgun).
+- **Carnet de Tir (Historique)** : Filtres par puces de type de cible et de date, cartes de séances avec pastilles de score colorées selon la précision.
+- **Setup de Session** : Sélecteurs rapides de distance (10m à 200m) et de coups par cible (3 à 30).
+- **Réseau & Export Serveur IA (Fix APK Mobile)** : Ajout des permissions `INTERNET` et `ACCESS_NETWORK_STATE` ainsi que `usesCleartextTraffic` dans le manifeste Android principal (`AndroidManifest.xml`) pour débloquer l'envoi vers le serveur IA et les IP locales depuis l'APK installée.
+
+## [v0.0.7] - 2026-08-26
+
+### 🚀 CI/CD & Déploiement Automatique (Gitea Actions)
+- **Pipeline de Release Android APK** : Compilation automatique de l'APK de production (`flutter build apk --release`) lors du push d'un tag (`v*`) et publication directe dans les Releases Gitea.
+- **Mise en cache persistante** : Sauvegarde des caches Gradle, Pub, Android NDK 28, CMake et SDK Platform pour des temps de build réduits à 1-2 minutes.
+- **Pipeline Backendia** : Déploiement continu automatisé du serveur backend et du dashboard lors des modifications sur `main`.
+
+### 🧠 Backend IA & Dashboard Web (Backendia)
+- **Architecture Tout-en-un** : API Express et Dashboard Next.js co-hébergés sur le même port sous `https://backendia.kevlar.cloud`.
+- **Validation OpenCV** : Certification et détection des anneaux de cibles concentriques.
+- **Journalisation & Modération** : Base SQLite avec historique complet des uploads, détection d'appareils, métadonnées et système de bannissement/débannissement de wallets.
+- **Dashboard Web** : Galerie de visualisation des photos de tir, éditeur de points/impacts et export global des datasets (ZIP / CSV).
+
+### 🔒 Sécurité & Reverse Proxy (YunoHost)
+- **Dashboard Privé** : Accès à l'interface d'administration protégé par le portail SSO YunoHost.
+- **API d'Upload Sécurisée** : Filtrage Nginx par en-tête secret `X-API-KEY` autorisant uniquement l'application Android.
+
+### 📱 Application Mobile Flutter
+- **Connexion Serveur Officiel** : Configuration par défaut sur `https://backendia.kevlar.cloud` avec transmission automatique de la clé d'API.
+- **Identité Anonyme & Stats** : Phrase de récupération de 15 mots, hachage SHA-256 du wallet et synchronisation du statut de modération.
+- **Expérience de Tir** : Nouveau flux de calibration, boutons de rotation fine, guidage au premier impact et popup de fin de session avec export IA intégré.
+- **Sauvegarde & Partage** : Export/Import JSON complet des sessions, statistiques et armurerie.
