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
