[PWGCF] Apply invariant mass cuts to cascade QA histograms

[tomasz-pawlaczyk]

Applied invariant mass cuts (invMCascade) to cascade QA histograms in doCascadeQA and doCascadeMCQA functions. Excluded hMassXi, hMassXiSelected, and hInvMpT to preserve full mass distributions.

The failing CI checks triggered by the O2 linter (pdg/explicit-code, magic-number, etc.) are due to pre-existing legacy code in this file, rather than the changes introduced in this PR. My modifications strictly apply the invariant mass cuts to the cascade QA histograms.

Could this PR please be reviewed?
