refactor: centralize all physical constants in constants.py, fix unit naming

Browse Source 
- Add EULER_GAMMA, ME_KEV, R0_FM to constants.py
- Replace hardcoded 0.511, 0.5772..., 1.2 with imports from constants
- Fix T_to_W parameter name: T_kev -> T_MeV (it takes MeV, not keV)
- Remove duplicate ME_ME from spectrum.py (import ME_MEV from constants)
- Remove hardcoded r_0 from detector_response.py and radiative.py
- Update CONVENTIONS.md to reference correct constant names
