PR description:
Follow-up to PR #35811.
Noticed that even in the CRAFT'22 DQM (post PR #35811 has been merged) data the Strip End Caps (TID / TEC) residuals are still empty (see e.g.: https://tinyurl.com/yd83lqlz and https://tinyurl.com/y8286jpa).
This has been traced down to the fact that in cosmics, unlike collisions (see:
cmssw/DQM/SiStripMonitorClient/python/SiStripSourceConfigTier0_cff.py
Lines 152 to 156 in 8204ef9

(making it impossible to get precise residuals in the endcap).This is fixed in this PR introducing the cosmics track refitter in the DQM configuration.
