fix: only set s3DownloadedFile when download actually completes

The s3DownloadedFile was being set immediately when download started,
causing the "Restore" button to appear while still downloading and
the download message to not hide properly.

- Remove immediate setting of s3DownloadedFile in downloadFromS3()
- Set s3DownloadedFile only in handleS3DownloadFinished() event handler
- Add broadcastWith() to S3DownloadFinished to send downloadPath
- Store downloadPath as public property for broadcasting
- Now download message hides and restore button shows only when complete
