fix: broadcast S3DownloadFinished event to hide download message

- Make S3DownloadFinished implement ShouldBroadcast
- Add listener in Import component to handle S3DownloadFinished event
- Set s3DownloadInProgress to false when download completes
- This hides "Downloading from S3..." message after download finishes
- Follows the same pattern as DatabaseStatusChanged event
