Get QA reporting data for an assistant instance

An AssistantInstance represents a single conversation between Luma's Navigator AI assistant and a patient (or staff member), spanning one or more channels such as a voice call, SMS, or chat. It tracks the lifecycle of that conversation as it moves from idle to in-progress to a terminal success or failure status, whether the patient's identity was verified, which entry points were used, and reporting data about the call's outcome and detected intents. AssistantActions attach to an AssistantInstance as the individual tool calls made during the conversation.
