Pull Request Overview

This PR modifies the vendor assignment history tracking mechanism to prevent duplicate records. The changes enable updating existing vendor assignment history entries instead of creating duplicates when the same vendor information (VAT ID, GLN, Address, Company Name) is already tracked.

• Added a secondary key to enable efficient lookup of existing vendor assignment history records
• Modified the insertion logic to update existing records or insert new ones based on whether a matching history entry exists
