     * Server-side GL code typeahead.
     *
     * Replaces the raw SELECT that went through SubQueryService:
     *
     *   SELECT hdr.guid FROM bl_fi_mst_glcode AS hdr
     *   WHERE hdr.status != 'DELETED'
     *     AND hdr.chart_of_acc_guid = '<coaGuid>'
     *     AND (hdr.gl_code_1 ILIKE '%<text>%' OR hdr.name ILIKE '%<text>%')
     *   ORDER BY hdr.gl_code_1
     *
     * GET glcode/query -> GlcodeUow.getByCriteria -> generateWhereClauseByCriteria
     * honours every part of it as criteria: `search_word` (bound, ILIKE),
     * `chart_of_acc_guid`, and a default of `status != 'DELETED'` when no status is
     * given. orderBy/order reproduce `ORDER BY hdr.gl_code_1` (that UoW defaults to
     * DESC, so `order` must be sent explicitly).
     *
     * Behaviour notes:
     * - `search_word` also ILIKEs gl_code_2..4, descr and txn_type, so the typeahead
     *   matches a little more than the old gl_code_1/name pair.
     * - One request now instead of one subquery plus one getByGuid per hit, and the
     *   container comes back from the same query rather than a follow-up fetch.
