Add oven/batch settings to job create and edit forms

CreateJobDto and UpdateJobDto now carry OvenCostId, OvenBatches, and
OvenCycleMinutes. The Create POST sets these on the new Job entity and
passes them to the pricing engine; the Edit GET populates them from the
existing job so the form reflects saved values, and the Edit POST writes
them back before repricing.

Both Jobs/Create.cshtml and Jobs/Edit.cshtml now include an Oven & Batch
Settings card (matching the quote form) with oven selector, batch count,
and cycle time inputs. The wizard init block now passes the selected
OvenCostId instead of null so live auto-pricing reflects the oven cost.

ViewBag.DefaultOvenCycleMinutes added to PopulateCreateEditWizardViewBagsAsync
so the placeholder in both views shows the company default.

Also fixed: NoExtraLayerCharge was missing from the Edit GET coat DTO
mapping (would have caused the flag to reset to false on next edit).
