Removal of ITEM_NOT_STOCKED_AT_LOCATION error

The ITEM_NOT_STOCKED_AT_LOCATION error will be removed from InventoryAdjustQuantities, InventoryMoveQuantities, InventorySetOnHandQuantities, and InventorySetQuantitiesUserErrorCode as of API version 2026-10.

Following the changes described here, inventory quantities can now be adjusted at any location. As a result, the condition that previously triggered ITEM_NOT_STOCKED_AT_LOCATION can no longer occur, and this error is no longer emitted.

This update removes an obsolete error code. If your app currently handles ITEM_NOT_STOCKED_AT_LOCATION, you can safely remove any logic that depends on this specific error.
