Error UX on aspera download / upload (lo-fi)

Upload failed at the Aspera level :
User can see that the upload wasn’t completed
(The nature of the error can be seen in the Aspera UI)
In the list view, items in errors are listed in a separate section
An option to retry this upload is visible on this section and below the overall transfer status
If all uploads are completed, the overall transfer status is set to “completed : ( x ) errors occurred” and an icon is a warning (not checkmark)

Upload failed during Nuxeo document creation step :
In the list view, items in errors are listed in a separate section
Error reason is listed after the document title
Clicking on the edit/error item shows the edit window, with the full error message.
If the error is related to invalid fields or field values (validation rules, formats…) the user can modify these values
An option to retry this upload is visible on the errors section and below the overall transfer status
