feat: initialiser le projet CVP (Next.js 14 + FastAPI + PostgreSQL)

- Frontend : Next.js 14 App Router, TypeScript strict, Tailwind 3, shadcn/ui, next-intl (fr/en)
- Backend : FastAPI, SQLAlchemy 2 async, Alembic, Pydantic 2, Python 3.11
- Infrastructure : Docker Compose (PostgreSQL 16 + Ollama)
- Tooling : ESLint + Prettier (frontend), Ruff (backend), pytest
- Structure complète des dossiers avec pages et routers placeholder
