Add pricing breakdown and powder pre-fill to Job Details; surface voided invoice history

- Job Details: collapsible internal pricing breakdown card mirrors quote details breakdown
  (items subtotal, shop supplies, discount, rush fee, tax, total)
- Job Details: voided invoice history section shows previous invoices instead of hiding them
- Complete Job modal: pre-fills powder usage from QR-scanned / manually logged entries so
  staff don't double-log; consumes pre-logged credit per InventoryItemId before deducting net delta
- JobProfile: map ShopSuppliesAmount, ShopSuppliesPercent, IsRushJob, DiscountType/Value/Reason
  so the pricing breakdown has the data it needs
