Money Handling Architecture: - Store all monetary values as integer cents (€105.91 = 10591) - Add app/utils/money.py with Money class and conversion helpers - Add static/shared/js/money.js for frontend formatting - Update all database models to use _cents columns (Product, Order, etc.) - Update CSV processor to convert prices to cents on import - Add Alembic migration for Float to Integer conversion - Create .architecture-rules/money.yaml with 7 validation rules - Add docs/architecture/money-handling.md documentation Order Details Page Fixes: - Fix customer name showing 'undefined undefined' - use flat field names - Fix vendor info empty - add vendor_name/vendor_code to OrderDetailResponse - Fix shipping address using wrong nested object structure - Enrich order detail API response with vendor info Vendor Filter Persistence Fixes: - Fix orders.js: restoreSavedVendor now sets selectedVendor and filters - Fix orders.js: init() only loads orders if no saved vendor to restore - Fix marketplace-letzshop.js: restoreSavedVendor calls selectVendor() - Fix marketplace-letzshop.js: clearVendorSelection clears TomSelect dropdown - Align vendor selector placeholder text between pages 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
