/**
 * Card-policy vendor search.
 *
 * Listens for `fetchCardPolicyVendorOptions` and hits the same
 * `/accounting/1.0/vendors` endpoint the Vendors-tab uses, but writes
 * results onto the dedicated `cardPolicyState.vendorSearch` slice — no
 * fan-out to the global `vendor` / `account` / `class` / `vendorList`
 * entities. That isolation is important: the user may be configuring a
 * card policy in parallel with browsing the Vendors tab, and we don't
 * want either flow to clobber the other's list state.
 *
 * Uses `switchMap` so the latest typed search wins — earlier in-flight
 * requests are abandoned, which is the right semantics for a
 * search-as-you-type UX.
 *
 * Consumers:
 *  - Manual `CardPolicyCreate / EditScreen`
 *  - AI CFO `CardPolicyInteractiveForm` (vendor step)
