MechaCat02 70a6598924 chore: harden docker-compose deployment (bind, memory limits, no-new-privileges) ...

- frontend publishes on ${FRONTEND_PUBLISH_ADDR:-127.0.0.1} not 0.0.0.0 (M4).
- mem_limit on backend(4g)/postgres(1g)/frontend(512m), .env-overridable (M3).
- security_opt: no-new-privileges on app + postgres services.
New knobs documented + allowlisted in the config meta-test; compose validates.
Deferred (need host verification): image pinning, backend healthcheck, cap_drop
on postgres/tor, Postgres backup sidecar.
