[FR] Add Processing Status/Progress Bar, and Tool Tip to Processing Icon

[kylepyke]

Is your feature request related to a problem? Please describe.

There is nothing in the UI (or logs) to indicate what type of processing is happening to newly uploaded files, how long it will take, or what file is currently being processed. There is also no description or tool tip for what the file status icons mean.

Describe the solution you'd like

Similar to the inset status window shown when uploading files, a dialog which shows what the software is doing would be helpful. Something indicating the type of processing, files left to process, remaining time, etc. The filesize of processed files should also grow in the UI to indicate actual size. Right now, the filesize doesn't change until the server is restarted, or the batch processing completes.

Describe alternatives you've considered

none

Additional context

This filesize is incorrect. It should read ~55gb, but ~15gb of files are still processing. No indication of status for the remaining files. What does this icon mean? When can I expect these files to be available?
