Document fixes from 2026-04-10 London network debugging session:
- pfSense WG now dual-stack (IPv4+IPv6 via HE tunnel gif0 pf rule)
- GL-iNet AllowedIPs must be single comma-separated UCI entry (parse bug)
- AdGuardHome/carrier-monitor must not use 1.1.1.1 (conntrack + rate limit)
- Expanded troubleshooting for site-to-site tunnel disconnects
