Default node_id is {hostname}_{random-per-boot}, so every boot
inserted a new services row and the console probed stale ones (409
node_id mismatch -> 'not found' node pages). Pin TURNSTONE_NODE_ID
(one upserted row) and TURNSTONE_ADVERTISE_URL to loopback — the
guest's slirp IPv6 lands in the SSRF guard's never-allowed lane.
Also drop the futile /etc/hostname baking (podman regenerates it at
boco build).
