feat: implement WebAuthn authentication for secure credentials
**Motivations :** - Replace PBKDF2 with WebAuthn for browser-native authentication - Enable secure credential storage using browser's built-in security - Require user interaction for credential generation - Store credentials in browser's credential manager **Modifications :** - Updated SecureCredentialsService to use WebAuthn instead of PBKDF2 - Added WebAuthn credential creation with platform authenticator - Implemented proper error handling for WebAuthn failures - Added fallback PBKDF2 method for compatibility - Fixed TypeScript errors in credential handling - Updated build configuration for WebAuthn support **Pages affectées :** - src/services/secure-credentials.service.ts (WebAuthn implementation) - vite.config.ts (WebAssembly and plugin configuration) - src/utils/sp-address.utils.ts (user interaction flow) - Build system (TypeScript compilation fixes)
