**Motivations :**
- Encrypt all wallet data with PBKDF2 key, never store in clear
- Detect security mode from available PBKDF2 key instead of using fallback
- Stop page without fallback if no PBKDF2 key is available
- Use existing PBKDF2 keys only, no generation
**Modifications :**
- wallet-setup.ts: Encrypt device data before storing, store only encrypted_device and encrypted_wallet
- wallet-setup.ts: Detect security mode by testing all modes to find a working PBKDF2 key
- wallet-setup.ts: Stop without fallback if no PBKDF2 key is found
- wallet-setup.ts: Retrieve existing PBKDF2 key (no generation)
- wallet-setup.ts: Remove separate security mode storage (already stored via PBKDF2 key in pbkdf2keys store)
- wallet-setup.ts: Add verification to reject any wallet stored in clear
- wallet-setup.ts: Fix IndexedDB inline key usage (remove explicit key parameter)
**Pages affected :**
- wallet-setup.html: Encrypts and stores only encrypted wallet data, detects security mode from PBKDF2 key
**Motivations :**
- Centralize database configuration to prevent version inconsistencies
- Fix service worker blocking during wallet setup
- Ensure all database stores are created at initialization
**Modifications :**
- Created database-config.ts with centralized DATABASE_CONFIG (name, version, stores)
- Updated storage.service.ts to use DATABASE_CONFIG and create all stores on upgrade
- Updated security-setup.ts to initialize database with complete configuration
- Updated wallet-setup.ts to call SDK directly and bypass service worker blocking
- Updated database.service.ts, webauthn.service.ts, and database.worker.js to use DATABASE_CONFIG
- Removed service worker dependency for wallet setup page
**Pages affected :**
- security-setup.html: Initializes database with all stores on page load
- wallet-setup.html: Saves wallet directly to IndexedDB without service worker dependency
**Motivations :**
- Implémentation du système de sélection de mode de sécurité
- Séparation claire entre les données de sécurité et les données du wallet
- Suppression des duplications entre 'encrypted-pbkdf2-key' et 'pbkdf2-key'
- Architecture modulaire pour la gestion des credentials
**Modifications :**
- Ajout du composant security-mode-selector pour la sélection du mode de sécurité
- Création des pages séquentielles : security-setup, wallet-setup, birthday-setup
- Implémentation des services de credentials (encryption, storage, webauthn)
- Ajout du service security-mode pour la gestion des modes de sécurité
- Correction du stockage des clés PBKDF2 avec le securityMode dynamique
- Suppression des méthodes redondantes dans StorageService
- Nettoyage des appels redondants dans secure-credentials.service.ts
