Description

add validate_psync_reference_id implementation for Noon as we can make a Psync using connector_request_reference_id and currently core is defaulting if connector_transaction_id is not present it fails the Psync.
Main PR: #2886

Additional Changes

• This PR modifies the API contract
• This PR modifies the database schema
• This PR modifies application configuration/environment variables

Motivation and Context

How did you test it?

Cant be reproduced in envs as either a timeout is required or would need to delete the connector_transaction_id in the DB.

Check for regular proper working of Psyncs in all the cases.
