fix: consider min order qty in the purchase/transfer flow of production plan

The transfer flow ignored Consider Minimum Order Qty twice: the JS
handler force-reset the checkbox before fetching items, and the
purchase remainder left after allocating transfers from other
warehouses was never raised to min_order_qty (the check runs on the
total requirement before the split).

Drop the JS reset and apply min order qty to the purchase remainder,
in stock UOM before the purchase UOM conversion.
