Confirm validation

Confirm annotation, switch status to exported (or exporting). If the confirmed state is enabled, this call moves the annotation to the confirmed status.

<Callout type="info"> The confirm call is the right choice when confirming correctly captured data and switching the annotations to `confirmed` or `exported` state. One can be tempted by patching the status of the annotation to the `confirmed` or `exported` state. However, patching status skips key annotation metadata updates which negatively affects the [Dedicated AI Engine](https://knowledge-base.rossum.ai/docs/ai-engines) training. </Callout>
