/**
 * #5005 — Per-combo editable `description` field.
 *
 * The routing-combo API historically had NO `description` field: the Zod
 * `createComboSchema` / `updateComboSchema` stripped any `description` on save.
 * This proves the schema now ACCEPTS and PRESERVES `description`, and that the
 * value round-trips through the DB layer (persisted in the `data` JSON blob and
 * surfaced back by GET-style reads), with no new DB column.
