Fixes of MinBias monitoring plots
This MS is a bunch of rather minor fixes to monitoring of MinBias (both online and DQ).
- tuning histogram limits
- added pt/eta histograms
- fixed names of monitored variables so all is filled (thanks to @algliber for reviewing reprocessing results and spotting those)
- detailed histograms are produced only for the primary chain Also fixed one bug in hypo tool. We were by default requiring that number of tracks is ">" that the threshold whereas we should be ">=". Related to ATR-23439
