Fix AI quote blast rate: single formula path, correct client preview

Browse Source 
Root cause: company-settings-lookups.js had its own baseByCfm/multiplier
tables that were completely different from ShopCapabilityCalculator.cs,
so the UI showed an inflated rate (e.g. 82 sqft/hr) while the AI prompt
received the server-computed rate (e.g. 9 sqft/hr).

- Add CompanySettingsController.DeriveBlastRate endpoint — thin GET that
  calls ShopCapabilityCalculator directly; now the single formula path
- Delete all client-side formula code (baseByCfm, multiplier tables,
  deriveBlastRate) — ~30 lines removed
- Modal live preview calls /CompanySettings/DeriveBlastRate with 250ms
  debounce instead of computing locally
- Blast setup table uses setup.derivedRate from GetBlastSetups (already
  server-computed) instead of recalculating client-side
- QuotesController.AiAnalyzeItem: when no blast setup is explicitly
  selected, fall back to the company's default blast setup so the
  configured rate is always used
