fix: Ignore rate limits for local/loopback IP traffic

[sds]

Why is this change needed?

When using a proxy in front of the hub you'll get rate limit errors even though the traffic is coming from different IPs.

Until we support the X-Forwarded-For, this is a quick way to unblock the use of reverse proxies like nginx or Caddy.

Related to #1721.
