Get prediction status
Poll a prediction until it finishes.
Keep polling until status is SUCCEEDED (or FAILED). A finished run
carries the cell_count detected. Pass its image_id and channel to the
/export/* endpoints. A non-UUID prediction_id is rejected with 422 before it
reaches the database.

Successful Response
A prediction's polling snapshot. cell_count is populated only once
status is SUCCEEDED; then pass image_id and channel to the
/export/* endpoints.
