Issue

While selecting or scanning a batch in the Delivery Note, an AttributeError was raised:

Traceback (most recent call last):

AttributeError: 'dict' object has no attribute 'selling_price_list'

This occurred because doc was being treated as an object but was actually a dictionary.

Fix
Updated the relevant code in update_stock to correctly access selling_price_list from doc.
