fix: consumption anomaly ignores sealed packs in other rows

getConsumptionPredictions now aggregates total qty across all
inventory rows for the same product_id before flagging.
If totalQtyAllRows >= expectedQty, the anomaly is suppressed
(stock is healthy, just split across opened+sealed rows).
Also uses aggregated total as the displayed actual_qty.
