[PWGJE] Add hasColl and collision-environment QA to jet cross-section efficiency

[Hamwooseok]

This PR adds optional QA processes to "jetCrossSectionEfficiency" to study the reconstructed-collision ("hasColl") inefficiency and its dependence on the collision environment.

1. processDataTVXBCEnvironmentQA

• Measures the data-visible TVX-BC environment using the number of other TVX BCs in the same ITS ROF, the nearest TVX BC distance, and FT0C activity.
• Provides a reconstructed-collision proxy for direct Data/MC comparison.

2. processMCEnvironmentQA

• Performs the corresponding visible TVX-BC QA in MC.
• Studies the dependence of "hasColl" on the truth collision environment.
• Compares the truth and TVX-visible environment and validates the reconstructed-collision proxy against the JetDerived "hasColl" definition.

3. processMCHasCollTrackFateQA

• Checks whether tracks originating from MC collisions that fail "hasColl" are still reconstructed, unassigned, or associated with other reconstructed collisions.

4. processMCHasCollJetSurvivalQA

• Studies whether MCP jets from "hasColl" and "noColl" collisions survive at detector level and how much of the reconstructed constituent momentum is captured by detector-level jets.

5. processMCHasCollJetEnvironmentQA

• Stores selected MCP jets as a function of the visible TVX-BC environment and "hasColl", allowing the jet-level "hasColl" efficiency to be reweighted to the Data collision environment.

All newly added QA processes are disabled by default. Data- and MC-only processes are explicitly separated, and the existing cross-section-efficiency selection logic is unchanged.

Hello @nzardosh. The build/O2Physics/staging check failed with No logs found, while the O2Physics build and other required checks passed. Could this be a CI issue, and should it be retriggered?
