Julien LutranandClaude Opus 5 7e6b8f2848 doc: make every LAN instance static, record the FTTH fallout
Follow-up to a7f1ac6. The Archer C7's DHCP reservations did not carry
over to the FTTH box, so anything still on DHCP was one lease renew away
from moving — as blocky already demonstrated by taking LAN DNS with it.
jellyfin-server and jellyfin-client are now static too; homeassistant
stays dynamic on purpose (it never had a reservation).

Records three things that cost time to find:

- jellyfin-client can never use netplan: the kiosk raw.lxc bind-mounts
  the host /run/udev read-only, so netplan generate fails and config
  silently does not regenerate at boot. It uses systemd-networkd now.
- LAPTOP719974 and patate also lost their reserved addresses.
- ks4 cannot serve as an IPv6 exit: it has a global v6 address and a
  default v6 route but no working v6 egress, so extending the torrent
  tunnel to ::/0 is not an option. IPv6 stays disabled in the container.

Also notes the C7 + LTE box kept as fallback: only the gateway differs.

Julien LutranandClaude Opus 5 a7f1ac691e doc: FTTH migration — gateway is now 192.168.0.1
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.

Julien LutranandClaude Opus 5 58dcaa5d41 nas: new storage host on A1SAi-2750F — 4 TB off USB onto SATA
Builds the box that ends the usb4t dropouts: the JMicron bridge was the
least reliable device in the setup and it held the intended off-site copy
of ks4. The 4 TB now sits on direct SATA as pool `tank`.

- OS on mdraid RAID1 across two 120 GB SSDs (Intel 330 + Toshiba Q300),
  both ESPs bootable; `incus` ZFS mirror on their tails, ~22% left
  unallocated as over-provisioning
- media at /export/media, exported read-only over NFSv4 to nuc
- transmission-bt moves here (its WireGuard tunnel is in-container, so
  ks4 needed no change) and writes to the dataset locally
- backup pools nucbackup / ks4backup / nasbackup
- monitoring live: msmtp (submission+auth, verified 250), zed with
  NOTIFY_DATA, zpool-health.sh every 15 min, smartd on all three disks

Traps recorded because none of them point at their own cause: booting
with the display active kills the i915 probe and wedges incus; d-i picks
grub-pc vs grub-efi from how the installer booted; `incus storage create`
hangs forever on a mountpoint=none dataset; the BMC is deliberately never
cabled, so there is no out-of-band console.
