Document teddycloud (pve_id 131) — closes the Week-3 drift finding

teddycloud was live on hubris (LXC 131, docker compose, TeddyCloud —
a Toniebox cloud reimplementation) but never made it into inventory.yaml.
Already referenced in passing by containers/132-rclone.md ("131 was
already taken by an undocumented teddycloud container") and
hosts/strong.md's migration changelog (a DHCP conflict fix), but no
inventory entry or doc page existed until oikos/drift.py's inventory-
vs-live check caught it.

Verified live via read-only SSH (pct config 131, pct exec 131 -- ...,
docker ps): hostname, static IP 192.168.8.150, 1 core/1GiB/16GiB rootfs,
Debian 12, runs via docker compose at /opt/teddycloud. No changes made
to the running container.

Also fixed: house's inventory notes claimed 192.168.8.212 is teddycloud's
current IP via DHCP — stale, teddycloud has a static IP now.

Flagged in the new container page: teddycloud has no Caddy forward-auth
gate, unlike sab.hubris.network on the same Caddyfile.

`python3 oikos/drift.py` no longer reports an inventory-vs-live finding
for pve_id 131. (A separate, pre-existing gap surfaced while verifying
this: rclone's own inventory.yaml block is missing pve_id/host/lan_ip —
out of scope here, flagging for a follow-up.)
