[BackPort CMSSW_15_0_X] Include scouting EGM in Online DQM stream

[tihsu99]

PR description:

A patch is added to include scouting egamma DQM monitoring in the online stream. The update is highly related to previous PR #48398 i.e. here we introduce scouting egamma part into HLT Scouting DQM online client for the DQMOnlineScoutingstream. This progress has been mentioned in the scouting meeting at 28 Aug 2025.

This is the backport of the approved PR for CMSSW_15_1_X: cmssw#48850 Include scouting EGM in Online DQM stream

Description of the current change

• Add options useOfflineObject in the config files under the original HLTriggerOffline/Scouting. In online stream, we could choose not to use any offline object by such options.

• Add EGM part to online stream config file accordingly.

• Note: The current file HLTriggerOffline/Scouting/python/HLTScoutingEGammaPostProcessing_cff.py, which corresponds to the DQM Harvester, uses offline objects to achieve more accurate Tag-and-Probe measurements. Therefore, this postprocessor is not included in the online DQM sequence. (Similarly, in previous PR, for scouting muons, the harvester defined in HLTriggerOffline/Scouting/python/ScoutingMuonMonitoring_Client_cff.py is not used in Online DQM.) This is mentioned here for completeness.

@mmusich @tihsu99 do you want us to deploy the PR in production before the release including it is built?

[mmusich]

do you want us to deploy the PR in production before the release including it is built?

If you can do that, it would be nice. If you change release can you pick up also #48790 ? Thank you.
