Update Account via Salesforce Composite API

Nexova continuously syncs B2B partner details from an external portal to Salesforce. You will construct a multi-part payload for the Salesforce Composite API that first uses a `QueryAll` operation to find an existing Account by its external ID, and immediately uses the resulting Salesforce ID to execute a `PATCH` update within the same transaction.
