Batch support for PUT /inventory/stocktaking/productline

Hi,

Today we need to update thousands of lines on a single stocktaking in a single operation.

Currently, the API forces us to issue a single PUT request for each line, like this:

HTTP PUT /inventory/stocktaking/productline/123 with payload

{
    "id": 123,
    "count": 7
}

We want a "batch" endpoint handling multiple lines in a single request, something like this:

HTTP PUT /inventory/stocktaking/productline with payload

[
  {
    "count": 7,
    "id": 123
  },
  {
    "count": 8,
    "id": 3231
  }
]

Can this be implemented before the next stocktaking season ?

Start by tracing the existing PUT /inventory/stocktaking/productline/{id} endpoint and its request handling. Define the batch endpoint's validation and response behavior, then verify that one request can update multiple product lines as shown in the issue.
