[Hubspot] Add de duplication for assosiations

[harsh-joshi99]

This update prevents duplicate associations from being included in a single batch request. The HubSpot API does not allow multiple references to the same association within the same batch, which was previously causing errors.

A new helper function has been added to de-duplicate associations before sending the payload to HubSpot.

There are some unrelated Prettier changes.
