[M23] Parent data mapping issue with schema changes to list

As a Developer,

I want to resolve the schema changes issue for ParentDataMappingDummyMasterIDs in M23, where it is now a list instead of a string, and address the issue with updating the ACL when WPC data with IsDummyParentMappingEnabled is set to true,

so that the system functions correctly with the new schema and ACL updates.

Testing Criteria:

Schema Update Handling:

• Modify the system to handle ParentDataMappingDummyMasterIDs as a list instead of a string.
• Ensure the ACL is correctly updated when WPC data with IsDummyParentMappingEnabled is set to true.-
• Perform thorough testing to validate that the schema change and ACL updates work as expected.
• Ensure that there are no regressions or unintended side effects from these changes.

• Code changes
• Code changes to be deployed on Dev. Environment
