Better status reporting for large file uploads

Currently the message is not very clear: is the model still uploading? Is it being processed server-side?

Not sure what happens when interrupting/closing the page while upload is in progress. Maybe a corrupted file that can’t be processed?

This doesn’t matter for small 10MB IFC files. But when dealing with >1GB files or multiple larger models it is important to know if I can close the browser tab or should I leave it open?
