Custom powder/incoming powder material cost now flows into a separate auto-generated 'Custom Powder Order' line item instead of rolling into individual item prices, so users can add shipping charges before the customer sees the total. A dashed yellow preview card in the wizard shows the material cost and lets users edit the total (including shipping) before saving. After first save the price is user-owned. Also fixes a fatal CSV import crash when FinalPrice contains a non-numeric value (e.g. 'false' from a spreadsheet formula): the job CSV importer now streams rows one at a time with a lenient decimal converter, treating bad values as $0 with a per-row warning instead of aborting the entire import. Updated HelpKnowledgeBase.cs and Help articles (Jobs, Quotes) with Custom Powder Order behavior and a new Data Import / Export section. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
