[LPD] [Correct] Use CalibrationError in notebook
Description
Error messages can now be shown, but only if using the CalibrationError class. This starts to use it.
I also added a NothingToProcess subclass, as we discussed earlier today. I haven't implemented any special behaviour for this in the job monitor, so for now it will just be treated like CalibrationError.
How Has This Been Tested?
The change in exception types is unlikely to affect anything, but I'll run the LPD correction in CI.
