doc: FTTH migration — gateway is now 192.168.0.1

Browse Source 
The Archer C7 at .2 is gone; the FTTH box at .1 is the gateway. Every
static holdout (nas host, nuc host, privoxy, transmission-bt) pointed at
the dead .2 and had no internet — the reported symptom was privoxy.

Also record two things the migration broke that were not obvious:

- DHCP reservations did not carry over. blocky held .254 by reservation
  on the C7; a lease renew on the FTTH box moved it and took LAN DNS
  down. It is static now. jellyfin-* are still DHCP on stale leases.
- The FTTH box advertises native IPv6. transmission-bt's tunnel is
  AllowedIPs = 0.0.0.0/0, so v6 egressed around the kill switch on the
  home address. IPv6 is now disabled in that container.

|---|---|---|---|
| blocky | 192.168.0.254 | — | unprivileged, autostart; DNS ad-blocker for the LAN. Moved from nuc 2026-08-30 so it survives nuc being powered off |
| privoxy | 192.168.0.11 | — | unprivileged, autostart; filtering HTTP proxy, listens on **:3128** (not privoxy's default 8118); static config in `/etc/systemd/network/eth0.network`, `DNS=192.168.0.254`. Moved from nuc 2026-08-30 |
