Update payloadFactory.js

Consistent Formatting: Used destructuring and spread operator for a more concise and consistent format, especially in the fordCreatePayload function.
Parameter Names: Used shorthand for object property assignment where applicable (keys, hms_id).
Semantic Improvements: Ensured all functions are following a consistent pattern and naming conventions.
