refactor(address-service): DOMA-12746 add self-link check before updating possibleDuplicateOf in upsertHeuristics

Add validation to prevent setting possibleDuplicateOf to the same address (self-link). Log warning when rootAddressId equals addressId and skip the update operation to avoid creating invalid duplicate relationships.
