feat: migrate Firebase → NestJS REST API backend

Replace all Firebase SDK (Auth, Firestore, Storage) with HTTP calls to backend.prosapp.co/api/v1: - New ApiService singleton (JWT token, GET/POST/PATCH/DELETE/upload) - auth_provider: Firebase Auth → /auth/login, /auth/register, /auth/phone/* - services_provider + calendar_services_provider → /services endpoints - professional_provider + professionals_provider → /professional-info, /users/professionals - profile_form_provider + professional_form_provider → /users/me, /storage/upload - cities/professions/settings providers → /cities, /professions, /settings - firebase_chat_repository → polling via /chats endpoints (3s interval) - firebase_score_repository → polling via /comments endpoints (10s interval) - professional_detail_provider → /users/:id + /professional-info/:id - dashboard_view: Firestore.add → POST /services - chat_view + rating_view: FirebaseAuth.uid → AuthProvider.user.id - Models: Timestamp → String for createdAt fields - google_fonts upgraded to ^8.1.0 (Dart 3.12 compat) - Remove firebase_core, firebase_auth, cloud_firestore, firebase_storage from pubspec Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
