Fix wrong IBL error IDs and broken service-record histograms in monitoring
This MR fixes a couple bugs in the PixelMonitoring package related to:
- Some erroneous error IDs of IBL (FE-I4), they were shifted by one integer
- IBL service-record monitoring, where the label strings were corrupted and some labels were not set at all due to wrong for-loop ranges
No other packages are affected, this is P1/offline monitoring code.
