Update Multiplier
POST/api/items/updatemultiplier
Tier: Public — stable, supported for third-party integration.
Updates the multiplier of an item addressed by id or by tag number.
Has no effect on Kanban-type items — Kanban multipliers are driven by scan events, so the
entity silently ignores the update, though validation still runs against the (unchanged) values
and the call still returns 200. See ItemController.UpdateQuantity(...) for the id-vs-tag addressing
quirk and the SKU-type validation matrix.

Returns the updated item. See Items.ItemDetailDto. When addressing by tag (see remarks on
ItemController.UpdateQuantity(...), which shares the same addressing behaviour), this endpoint returns
HTTP 200 with a null body even though the update succeeded.
The item does not exist (NotFound); the multiplier does not satisfy the SKU type's rules
(InvalidOperation, field Multiplier); or UpdateItemMultiplierDto.ItemId
was omitted.
