Returns internal transfer purchase orders that reserve inventory for a SKU from a source warehouse

Internal transfers reserve stock on the source (supplier) warehouse until they are completed. Returns purchase orders where the supplier warehouse matches the given warehouse (resolved to its physical warehouse when virtual) and an order line matches the given SKU, excluding purchase orders in status Completed, Deleted or OrderCanceled.

By default only transfers that actively reserve warehouse stock are returned: purchase orders created within the last two years (the reserved-quantity calculation window) whose order line for the SKU is not fully cancelled and not fully delivered. Partially delivered transfers are included, since they still reserve the undelivered remainder. Set includeAll=true to also return the excluded purchase orders, mirroring the "Show all" toggle in the reserved-inventory dialog.

Each purchase order is enriched with the properties hasCancelledLines, isDelivered and isPartiallyDelivered, computed for the given SKU. Sorted by created date, descending.
