[Webservice] Create correction reports in MyMdC when jobs have finished

Description

MyMdC now has space for reports associated with each run (planning#185). This is meant to be used for reports from corrections. So now we need to add the details when an execution has finished and a PDF report created.

Closes planning#189

How Has This Been Tested?

Deployed under xcaltst and recalibrated a CALLAB run: https://exflmdtest.desy.de/test_metadata/proposals/259/runs/91672#run-reports
