feat: Phase 1 — socle backend FastAPI + frontend Next.js

Backend (FastAPI + SQLAlchemy): - Modèles : User, Client, Audit, Cible, Vulnérabilité, Action - Auth JWT (register/login/me) avec bcrypt - Routes CRUD complets : clients, audits, cibles, vulnérabilités, actions - Schémas Pydantic v2, migrations Alembic configurées - Rate limiting (slowapi), CORS, structure scanners/reports pour phase 2 Frontend (Next.js 14 App Router): - shadcn/ui : Button, Input, Card, Badge, Label - Page login avec gestion token JWT - Dashboard avec stats temps réel - Pages Clients (grille) et Audits (liste) avec recherche - Layout avec sidebar navigation + protection auth - Dockerfiles multi-stage (backend + frontend standalone) Infrastructure: - docker-compose.yml : postgres, redis, backend, frontend - docker-compose.prod.yml avec labels Traefik - .env.example complet - .gitignore mis à jour Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
