Instructions

Reconcile inventory closing balances

An operations team needs to reconcile closing inventory from inventory_opening and inventory_movements. Closing units equal opening_units plus every signed quantity_change. Preserve products that have no movements.

Return exactly two columns: product_id and closing_units. Return one row per product, ordered by product_id.
