- Around line 129-130: Update NormalizeTrustedProxyCIDRs to detect IPv4-mapped
IPv6 networks after net.ParseCIDR: convert prefixes from /96 through /128 to
equivalent IPv4 CIDRs, and reject mapped prefixes shorter than /96 instead of
storing them. Preserve normal IPv4 and non-mapped IPv6 handling, and add
coverage for ::ffff:10.0.0.0/120 and rejection of ::ffff:10.0.0.0/8.

I spoke with AI about this PR. My conclusion is that I can merge it and slightly refactor/adjust(make a few things slightly more configurable) OR if you want, you can improve it at this PR. Let me know which option do you prefer. Mr AI told me:

My feelings will not be hurt if you refactor or even completely rewrite this from scratch. I'm just focused on the outcome 😆 I should say after looking through that blurb, my immediate use case is in my home lab where the clients have private IPs, but in a different range than my k8s cluster (where gomodel and my reverse proxy is running). So as long as I can only use some of the private IP space CIDRs instead of all of it, it will suit my needs. It almost seemed like it was suggesting to include all private IP space by default |

Thanks for expressing your use case :) It helps! Merging this one and probably I'll modify this part a little bit soon! |
Replaces LOGGING_TRUSTED_PROXY_CIDRS (unreleased, added in #1049) with SERVER_TRUSTED_PROXIES, SERVER_CLIENT_IP_HEADER, and SERVER_TRUSTED_HOPS. The old key is not accepted.

@iggy FYI, the configuration shape was changed slightly here. It will be released today OR tomorrow. That's the way it could be configured: https://github.com/ENTERPILOT/GoModel/pull/1061/changes#diff-749e06f64632f62a0c0dfbf4c4f3850e27e94ac109aa121fabd5c29469ae88de (or just ask your AI agent about that how to set up it properly :) |

Description
Add support for allowing GoModel to show the real client IP in audit logs. It works by extracting the first IP from x-forwarded-for headers that isn't in a new trusted cidrs setting
