Viktor Barzin e9046e5a26 traefik+pfsense: real IPv6 client IPs via HAProxy PROXY-v2 bridge
Replace the pfSense socat IPv6 forwarder (which masked every IPv6 client
as 10.0.20.1) with a standalone HAProxy bridge using send-proxy-v2, so
real IPv6 client IPs reach Traefik/CrowdSec. Traefik now trusts PROXY-v2
only from 10.0.20.1 on the web/websecure entrypoints; real IPv4 clients
(ETP=Local, own source IP) are unaffected. Mail-over-IPv6 routed through
the mail NodePorts (send-proxy-v2) too. Bridge is TCP/h2 only (no QUIC
over IPv6). Persistence on pfSense: rc.d/ipv6proxy + ipv6_proxy.sh
(config.xml shellcmd), keeping the nginx-off-[::] patch.

Also fixes stale networking.md: Traefik was still documented on the
shared .200; it moved to dedicated .203/ETP=Local on 2026-05-30.
