PIMS-1889: Timeout the loading spinner when credentials are missing

[GrahamS-Quartech]

🎯 Summary

PIMS-1889

Added an automatic timeout to the loading spinner so that you will be automatically prompted to log in again if it seems like your credentials never got loaded. Also added a little message box so that users know to just wait a sec if they are seeing the loading spinner. A bit hacky, but the user experience is not too bad I think.

Works as expected, no hanging circle loader. Message looks good. No issues found.
