Add remaining-weight input mode to inventory scan/usage page

Users can now toggle between 'Amount Used' and 'Remaining Weight' on the
QR scan page. In remaining-weight mode, usage is calculated as
(current stock - remaining) before submit — no controller changes needed.
Includes live hint showing calculated usage and new balance as they type,
with validation preventing negative usage or remaining > current stock.

+### Pricing Routing Flags — Must Stay In Sync Across All Three Layers
+
+`PricingCalculationService.CalculateQuoteItemPriceAsync` routes each item to the correct pricing path using boolean flags. **These flags MUST exist identically on `QuoteItem`, `JobItem`, and `CreateQuoteItemDto`, AND be mapped in all three `JobItemAssemblyService.CreateJobItem` overloads.**
+
+| Flag | Effect if missing on JobItem |
+|------|------------------------------|
+| `IsAiItem` | Job repriced as calculated item; oven cost double-charged on every save |
+| `IsGenericItem` | ManualUnitPrice ignored; price recalculated from surface area |
+| `IsLaborItem` | Item repriced at surface-area rate instead of hours × labor rate |
+| `IsSalesItem` | ManualUnitPrice ignored; item repriced using coat/surface math |
+
+**Checklist when adding a new pricing routing flag:**
+1. Add the property to `QuoteItem` (Core/Entities)
+2. Add the property to `JobItem` (Core/Entities)
+3. Add it to `CreateQuoteItemDto` (Application/DTOs)
+4. Add it to `JobItemSeed` (private class in JobItemAssemblyService)
+5. Map it in all three `JobItemAssemblyService.CreateJobItem` overloads
+6. Include it in every `existingItemsData` JSON block in job views (`Edit.cshtml`, `EditItems.cshtml`) and in all job controller actions that build `CreateQuoteItemDto` from a `JobItem`
+7. Add a migration if the field is new on a persisted entity
+8. The structural test `PricingRoutingFlags_ExistOnBothQuoteItemAndJobItem` in `JobItemAssemblyServiceTests` will fail until steps 1–3 are done — this is intentional
