Subject: [PATCH] feat: add shipment request (C-013) and allocation request
 (C-014) cart workflows

Multi-step cart workflows for both shipment and allocation requests:
- Ship-to address selection from Epicor portal_CustomerShipToAddresses
- Inventory browser dialog (shipment) / coil browser dialog (allocation)
- Cart persistence in DB with duplicate detection
- Details form (order#, PO#, pickup date, instructions, email recipients)
- Review & submit with confirmation dialog
- Cancel with permission gate and confirmation
- Shared components: stepper, ship-to selector, cart table, header form, review
- 16 API routes, 4 services, 13 components, 6 pages
- Phase 2 complete: 16/16 tasks done
