Recalculate or update price in the work order when modifier fields change (e.g. additional mold samples)

Users want the work order to update the price when they change fields that affect the fee—such as the number of additional mold samples—instead of the price staying as a static number from when the order was booked. Right now, auto-calculation only happens on the scheduling form; once the order is confirmed, the price in the work order doesn't recalculate when those required or modifier fields are changed, so staff have to manually adjust the price or re-enter to get the right total.

Why it matters: Inspectors and office staff need the work order to show the correct fee when add-ons or quantities change after booking, so they don't undercharge or have to fix prices by hand.
