Warning and tool to delete data if > 70% of disk space is used

We should however have a button to actually delete data (e..g the local "scratch" dir.
In this case, check however if there are calculations running and skip them? Or ask them simply to stop any running calculation, then we simply delete the whole folder.

Possibly a second button to completely delete the profile and create a new one, including DB and disk-objectstore, clarifying consequences.)

This above in the home app. In addition, in the QE app, we can have a warning close to the submit button, if the disk is almost full, warning that things might fail and they should free up space
