anti 53d08e01e5 feat(systemd): decnet-canary.service unit + tests ...

Worker unit mirrors decnet-webhook.service shape: simple type, runs
as the decnet user/group, append-style log file, full security
hardening (NoNewPrivileges/ProtectSystem/ProtectHome/PrivateTmp/
LockPersonality + the rest). Added /var/lib/decnet to ReadWritePaths
because the API process persists operator-uploaded canary blobs there.

CAP_NET_BIND_SERVICE granted (ambient + bounded) so an operator who
overrides DECNET_CANARY_DNS_PORT to 53 or HTTP_PORT to 80/443 in
.env.local doesn't need to fight systemd. The defaults stay
unprivileged (5353 / 8088).

Added decnet-canary.service to decnet.target so 'systemctl start
decnet.target' brings it up alongside the rest of the workers.

decnet init auto-discovers deploy/decnet-*.service.j2 files (per
decnet/cli/init.py:_install_units) so no further wiring needed —
running 'decnet init' on a fresh host installs the new unit.

Static tests confirm the unit references decnet canary, depends on
the bus, carries the standard security directives, and is listed
in the master target.
