Adding "Include UOM" in Reports with Qty and Rates (#15541)

* Added Include UOM field for Stock Balane, Stock Ledger and Stock Projected Qty

* Add columns in result list-of-lists instead of converting reports to list-of-dicts

* For requested changes
-Merged conversion factor query with item detail queries
-Ensuring snail_case
-Made columns consistently list-of-dicts
