[PWGHF] Make D0 dual-hypothesis rejection configurable

[swapneshkhade]

Changes:

• Make the rejection of candidates satisfying both the D0 and D0bar hypotheses configurable in the downstream D0-hadron correlation task.
• Apply the configurable rejection consistently in data and MC-reconstructed processing.
• Add hypothesis-specific prompt, non-prompt, and background ML-score selections.
• Propagate the D0 and D0bar non-prompt ML scores through the candidate correlation table.
• Introduce dedicated D0 pT bins for the ML working-point thresholds.
• Apply the corresponding hypothesis-specific ML selection to the MC-reconstructed signal, reflection, and background distributions.

This allows the analysis to be run both with and without rejecting candidates satisfying both hypotheses, enabling the physics impact of the rejection to be evaluated.
