Feature: Show source in the completion message for file transfer operations

### Description

After a file transfer is complete, the dropdown from the Status Centre icon only shows that files have been moved. It does not show the name of the file or folder that was transferred, which makes it very difficult to identify which operations have completed if many are occurring at once.


### Requirements

After copying items, the status center should display the source location in its completion message.
