[TTAHUB-3912] Support multiple grant replacement and ensure all grants being replaced have the same region and recipient

[AdamAdHocTeam]

Description of change

So when looking into the CDI grant replacement code in updateGrantRecipients job. We currently were not supporting the updating of multiple grants becoming the single CDI replacement (many to one).

This change allows us to replace multiple grants with a CDI as long as they all have the same recipient and region id.
