Refactors `StockPickingRecordModel` to use generic `fromJson` utility functions for robust JSON deserialization, gracefully handling null or unexpected values for various fields.
Updates the stock picking API call to filter by `picking_type_code` ("incoming") instead of a hardcoded `picking_type_id`, enhancing clarity and maintainability.
Removes unnecessary `id`, `jsonrpc`, and `method` parameters from the API request and the `userId` field from the model.
