Get project reimport status

        Poll the status of an asynchronous project reimport operation.
        
        **Usage:**
        1. When you POST to reimport tasks, you'll receive a response with a reimport ID
        2. Use that `reimport_id` with this GET endpoint to check the reimport status
        3. Poll this endpoint to see if the reimport has completed, is still processing, or has failed
        4. **Reimport errors and failures will only be visible in this GET response**, not in the original POST request
        
        This endpoint returns detailed information about the reimport including task counts, status, and any error messages.
        While a reimport is running, `task_count` / annotation / prediction counts update as batches commit.
        Counts are cumulative so far; there is no expected total, so percent-complete / ETA is not available from this API.
