/**
 * NAT/DDNS HTTP routes — thin adapters around `NatHandlers`
 * (`createNatHandlers(service)`). Side-effects (settings change, reachability
 * re-test, DDNS reconfiguration, a manual forward) emit a `connectivity-changed`
 * bus event. The service's own change listener covers the changes that happen
 * on their own (a mapping completing after a spawn, an IP change) — see
 * `server/index.ts`.
 *
 * Mount path: `/nat/*` — matches the existing CLI (cadre-host nat ...).
