The differential luminosity diagnostic was not valid for particles with mass 0. This PR generalizes the code for photons by expressing the center-of-mass energy with the 4-momentum: <img width="334" alt="Screenshot 2024-09-06 at 9 27 33 PM" src="https://github.com/user-attachments/assets/1100fce4-7043-44f7-91e9-73f6c9272799"> which is valid for photons as well.

This is done by extracting an base input script from the existing luminosity test involving **electrons and positrons**, and creating an input script involving photons that leverages the base input script.
