/**
 * Tests for procurement manager's buildFilterWhere function.
 *
 * Since buildFilterWhere is not exported directly, we test it indirectly via
 * the exported procurement methods (fetchPages, search, count, etc.) which
 * all call buildFilterWhere internally. The prisma mock is a Proxy that records
 * calls, so we verify the filter logic works as expected through manager method
 * calls.
 *
 * We also test CatalogFilterOpts interface coverage via type assertions.
