Preview the multi-warehouse sourcing plan for an order (no reservation)
Returns the proposed per-line multi-warehouse sourcing plan WITHOUT reserving any stock.
For each physical line, the system proposes which warehouse fills how much (preferred
order location first, then warehouses with the most available stock). Read-only: it
writes no inventory, creates no reservations, and posts no journal entry. Use it to
review a split before committing it via POST /orders/{id}/allocate. The manual
transfer path remains the override (ALLOCATION-MULTI-WAREHOUSE-SOURCING-AND-SOFT-VS-FIRM-RESERVATION).
Requires orders:read scope.
