stock flow API improvements

improve tracking and differentiation of API actions, you can implement a system that assigns reason codes and reason names for each stock flow. This will help clearly distinguish different actions without relying on user comments. Here's how you can approach it:

1. Define Standardized Reason Codes

Assign a unique code for each key action or API event.

For example:

ASN Received: CODE_001

Stock Increase: CODE_002

Stock Decrease: CODE_003

Damage : CODE_004

Quarantine : CODE_005
