Fix fulfillment consumables pricing architecture

- Add pricePerUnit field to Supply model for seller pricing
- Fix updateSupplyPrice mutation to update pricePerUnit only
- Separate purchase price (price) from selling price (pricePerUnit)
- Fix GraphQL mutations to include organization field (CREATE/UPDATE_LOGISTICS)
- Update GraphQL types to make Supply.price required again
- Add comprehensive pricing rules to rules-complete.md sections 11.7.5 and 18.8
- Fix supplies-tab.tsx to show debug info and handle user loading

Architecture changes:
• Supply.price = purchase price from supplier (immutable)
• Supply.pricePerUnit = selling price to sellers (mutable by fulfillment)
• Warehouse shows purchase price only (readonly)
• Services shows/edits selling price only
