/**
 * Port-scoped global reservations list — locks in feat(marina): the new
 * `GET /api/v1/berth-reservations` endpoint that powers the
 * `[portSlug]/berth-reservations` page. The route is thin (parseQuery →
 * listReservations); the test guarantees port scoping at the handler
 * boundary so a future refactor of the service can't accidentally leak
 * cross-port rows.
