Fix: Process partial_metrics on completed status

News and sentiment metrics were not appearing because the polling
loop only processed partial_metrics during WORKING status. When the
task transitioned to COMPLETED, the final poll returned immediately
without emitting the remaining metrics from the last sources.

Fix: Also process partial_metrics when status is 'completed' to
ensure all metrics (including news and sentiment) are captured.
