[14.0.X] add a python compilation unit test for DQM online clients

[mmusich]

backport of #44412

PR description:

In preparing #44385 I noticed that the test coverage of DQM online clients is somewhat poor since the existing unit tests do not contemplate all the possible run keys that can be exercised at P5.
It would be costly in terms of execution time and in terms of storage space (to store the input RAW data / streamer files) to cover all the possible uses cases in a battery of unit tests that actually execute cmsRun of these configurations, but at least they could be compiled to spot obvious configuration problems (as the ones resolved in #44384).
This is proposed in this PR.
In order to make the new unit test run, some leftover configuration issues have been fixed. I assume they are somehow irrelevant as they pertain to combinations that are probably never run online, but nevertheless to avoid too much ad hoc handling in the test they are fixed here.

PR validation:

The newly added unit tests: scram b runtests_TestDQMOnlineClients-compilation_[*] run fine.

[*] = 'pp_run','pp_run_stage1','cosmic_run','cosmic_run_stage1','hi_run','hpu_run','commissioning_run'
