Activity page: Error message required when NCBI API for PDF failure
We've had a problem with PDF generation due large file size. BUT the real problem is not being told about it. The manuscript stayed in tagging and didn't display an error message so helpdesk didn't know what the problem was. see activity pages for EMS83274 and EMS83205.
Also see EMS82049.
We need to display a file size error message here, preferably one which tells us which file is the problem as we can't see file sizes at a glance.
Thanks @parkinm for diagnosing the issue
