This MR is related to this ticket: https://redmine.xfel.eu/issues/161355 There was a need to overwrite the gain mode value for Jungfrau through proposal configurations.
This was not possible easily as the manual edit is different for Jungfrau notebooks because all conditions need to be manually edited because they are conditioned by only one flag, unlike other detector notebooks.
This MR separates every operating condition with its own flag. It uses -1 as a default value for the parameter to read it from files.
