get_secondary_items_from_job_card selected item_name/description/stock_uom/
bom_secondary_item alongside `group by item_code, secondary_item_type` (and an
orderby on the non-grouped idx) -> arbitrary pick on MariaDB, GroupingError on
Postgres. Wrap the non-grouped columns in Max() (Min(idx) for the orderby);
they are item attributes / the secondary-item BOM link, constant per group, so
MariaDB output is unchanged.
