Write an Express middleware in TypeScript to authenticate requests using JWT. The middleware must: check the Authorization Bearer header, decode and validate the token with the secret key, attach the decoded user to req.user, return explicit 401/403 errors, and handle token expiration.

Pour une meilleure maintenabilité, isolez la validation du token dans une fonction utilitaire dédiée. Utilisez `jsonwebtoken.verify()` avec `process.env.JWT_SECRET` et augmentez le type Express `Request` pour ajouter `user`. Gérez l’expiration via l’option `expiresIn` côté émission.
