feat: migrate prosappco from Firebase to NestJS REST API (Fase 2)

- Replace all Firebase* repositories with Api* repositories using HTTP + SharedPreferences JWT - Remove Firebase.initializeApp() and firebase_messaging background handler from main.dart - Update DI (app_di.dart) to inject Api* repositories instead of Firebase* ones - Replace all Timestamp/cloud_firestore usage with ISO 8601 String dates - Stub PhoneVerificationService (Firebase phone OTP → backend OTP when implemented) - Add ApiService singleton with JWT management in lib/services/ - Legacy firebase_*_repository.dart files preserved for Fase 4 cleanup Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
