     * Replaces the raw SELECT that went through SubQueryService:
     *
     *   FROM bl_fi_mst_entity_ext ext LEFT JOIN bl_fi_mst_entity_hdr hdr
     *   WHERE hdr.status = 'ACTIVE'
     *     AND (ext.param_code IN ('SUPPLIER_CODE','EMP_SUPPLIER_CODE')
     *          OR (ext.param_code = 'AKN_ETY_CTG' AND ext.value_string = 'SUPPLIER'))
     *     AND ((ext.param_code = 'SUPPLIER_CODE' AND ext.value_string ILIKE '%x%')
     *          OR hdr.name ILIKE '%x%')
     *   ORDER BY hdr.name
     *
     * This options object is used with SupplierService, whose endpoint is
     * entity/suppliers; EntityController sets is_supplier = true from that path
     * segment, so the "is a supplier" scoping the ext join expressed is applied by
     * the endpoint itself. EntityUow.whereClauseCriteriaForSnapshot (the method
     * behind GET entity/suppliers/query) then applies:
     *   - search_word -> EntityUowHelper.generateSearchWordCondition, which, with
     *     is_supplier set, ILIKEs hdr.supplier_code alongside name, id_no,
     *     nickname, descr, phone, email, website_url, tax_reg_number, ...
     *   - status -> EntityUowHelper.whereClauseHdr (`hdr.status = 'ACTIVE'`).
     *
     * Behaviour notes:
     * - The keyword now also matches phone/email/id_no/etc., not just supplier code
     *   and name, so the typeahead is broader than before.
     * - Entities recognised as a supplier only through the legacy extension rows (a
     *   `SUPPLIER_CODE` / `EMP_SUPPLIER_CODE` row, or `AKN_ETY_CTG = 'SUPPLIER'`)
     *   rather than through hdr.is_supplier are kept by the `legacy_entity_category`
     *   criterion, which makes EntityUowHelper.whereClauseHdr OR the same extension
     *   test onto the is_supplier condition. Without it those entities would drop out
     *   of the dropdown, because the endpoint derives is_supplier from the path.
     *   It costs a correlated subquery per request: once
     *   `entity-category-flag-check.sql` reports a zero gap for every tenant, the flag
     *   is backfilled and this criterion can be dropped.
     * - ORDER BY hdr.name is expressed through the sort criteria in the base class,
     *   which orders by the endpoint default; see DropDownComponent.searchEntity.
