Fix price override ignored for catalog items; fix time entry delete UI

- QuotePricingAssemblyService: catalog no-coat items now respect PowderCostOverride instead of always using DefaultPrice
- PricingCalculationService: removed duplicate catalog fast-path in CalculateQuoteTotalsAsync that bypassed CalculateQuoteItemPriceAsync (and thus ignored PowderCostOverride); all items now go through the single authoritative path
- Jobs/Details.cshtml: timeTracking.del() and timeTracking.save() now call costing.load() after success so the time entry row and costing breakdown stay in sync
