Fix TypeScript errors and display issues

**Motivations:**
- Corriger les erreurs TypeScript dans secure-credentials.service.ts qui empêchaient le chargement du module
- Résoudre l'affichage cassé des pages de setup en utilisant une redirection directe
- Supprimer le mode 'browser' et nettoyer le code mort

**Modifications:**
- Correction de la méthode inexistante getEncryptedKey() dans secure-credentials.service.ts
- Correction de la redéclaration de variable encryptedKey dans generatePBKDF2Key()
- Suppression des références au mode 'browser' supprimé dans security-mode.service.ts
- Ajout des propriétés requiresOTP et requiresPassword dans l'interface SecurityModeConfig
- Suppression de la méthode retrieveKeyFromBrowser() non utilisée dans storage.service.ts
- Changement de stratégie de routage pour les pages de setup (redirection directe au lieu d'injection)
- Mise à jour des textes des options de sécurité (Proton Pass → Clé de sécurité, OTP → code à usage unique)

**Pages affectées:**
- src/services/secure-credentials.service.ts (correction des erreurs principales)
- src/services/security-mode.service.ts (correction des références au mode browser)
- src/services/credentials/storage.service.ts (suppression de la méthode non utilisée)
- src/router.ts (changement de stratégie de routage)
- src/pages/security-setup/security-setup.html (mise à jour des textes)
- src/pages/wallet-setup/wallet-setup.html (mise à jour des textes)
- src/components/security-mode-selector/ (suppression du mode browser)
- src/pages/home/home.ts (suppression du mode browser)
- src/services/service.ts (suppression du mode browser)
