Includes: - CustomItemTemplate entity, migration (AddCustomItemTemplates), IUnitOfWork repo - IsCustomFormulaItem / CustomItemTemplateId / FormulaFieldValuesJson flags on QuoteItem, JobItem, CreateQuoteItemDto; mapped in all 3 JobItemAssemblyService overloads and all existingItemsData JSON projections + pageMeta blocks - ICustomFormulaAiService / CustomFormulaAiService: Claude-powered formula generator (natural language + optional diagram image) and NCalc2 evaluator - CompanySettings CRUD endpoints: GetCustomItemTemplates, Create/Update/Delete, UploadTemplateDiagram, TemplateDiagram (blob serve), EvaluateFormula, GenerateFormulaFromAi - Company Settings "Custom Formulas" tab + cfModal + company-settings-custom-formulas.js - item-wizard.js: formula item type card, renderFormulaFields, wzFormulaRecalc (live evaluate via POST), collectStep2 formula branch, buildCardHtml / emitHiddenFields - Formula badge in Quotes/Details and Jobs/Details; AI badge gap fixed in Jobs/Details - Help article (CustomFormulaTemplates.cshtml), Help Index card, HelpController action, HelpKnowledgeBase entry; 225/225 unit tests passing Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
