Get bulk-delivery job status for originators

Search and list individual loan originators (LOs — NMLS-registered mortgage loan officers) with filters — one row per originator. Filter by name, NMLS ID, location (state, city), employer/company, and production metrics (loan volume, units, product mix), with sorting and cursor pagination. LOCATION SEMANTICS: the state/city filters match an originator's PRODUCTION GEOGRAPHY — the markets where they actually originated loans in the selected period — not where their office or employer sits. An LO who lends across several markets matches a filter for ANY of those markets, while the `state`/`city` returned on each row reflect only their PRIMARY (highest-volume) market. So a search for city "Long Beach" can return an LO whose displayed location is a different city/state (e.g. their top market is in Arizona) — they still originated loans in Long Beach, it just isn't their #1 market. To rank originators by their volume within a specific market, sort by volume after filtering, or use the per-originator city/county/state breakdown endpoints. NEWLY LICENSED / NO PRODUCTION: an originator who is in the NMLS registry but has no production record is returned only by an identity search — `nmlsId`, `name` or `namePrefix` as the ONLY filter — sent with `producersOnly: false`. Those rows come after the rows that have production, carry `hasScoredData: false`, and have `null` production fields. Under any other filter, or without `producersOnly: false`, they are not returned (use `getOriginator` for one by NMLS id). This is the per-originator record search: use it to find specific loan officers or build a filtered LO list. (For a single originator by NMLS ID use the originator detail endpoint.) If you only need how many originators match and not the records themselves, send the same request body to `countOriginators`.
