fix(missions): egress from a subnet of their own, so the host can police it

docs/MISSION-EGRESS.md measured that a mission container reaches the entire
tailnet and SSH on its own host, and left the remediation unapplied. Applying
it on 2026-09-18 found why five iptables lines were never going to be enough:
missions egressed from clawmates_edge, the SERVER's network, and the server
needs the tailnet — Beszel on architect, Ollama for the local backend, the
node daemons for exec-test and node-placed terminals. A tailnet drop scoped to
172.23/16 cut the server off from architect:8090 inside a minute.

Missions now egress from clawmates_missions, 172.25.0.0/16, pinned so the
firewall can name it and declared in both compose files with the same shape
edge has. Compose v1 does not create a network no service uses, so on gw-04
it was created by hand with compose's own labels; the server's attach failure
message now says to check for it. core is unchanged: the door and API are
still reached over 172.20.

The policy itself (/usr/local/sbin/clawmates-egress.sh on gw-04, systemd unit
+ drop-ins on docker and tailscaled) lives in mangle/PREROUTING with
--ctstate NEW. Two earlier placements failed measurably: filter/FORWARD loses
to tailscaled re-inserting ts-forward above it on every restart, and
raw/PREROUTING runs before conntrack, so it dropped the server's replies to
tailnet clients and took the API off 100.102.112.85:8088. Verified from the
mission subnet (tailnet, host ssh, link-local blocked; public and core open),
from edge (tailnet open, ssh blocked), and inbound from tank; and proved to
survive restarting both daemons.

Also: deploy/compose/docker-compose.override.yml is tracked now. It holds the
fixes for the five local bring-up gaps and every credential in it is a
${VAR:?} reference, and it had lived on one laptop that lost a volume this
week.
