feat: Améliorer la gestion WebAuthn avec détection du contexte sécurisé

- Ajouter vérification du contexte sécurisé (HTTPS) pour WebAuthn
- Implémenter fallback pour le développement HTTP local
- Améliorer les messages d'interface pour expliquer le mode WebAuthn
- Ajouter logs informatifs pour le debugging WebAuthn
- Gestion d'erreur robuste avec fallback automatique
