The True-Client-IP header is set by Cloudflare and is only trustworthy
when behind a Cloudflare proxy. In non-Cloudflare deployments, this
header is attacker-controlled and can be used to spoof IP addresses.
Moving the middleware into the saas engine ensures it only loads for our
Cloudflare-fronted production deployment, not for self-hosted OSS
instances.
