Introduces `discrete_gaussian_dpsgd_event` in `jax_privacy/experimental/accounting.py` to model DP-SGD with discrete Gaussian noise using `ZCDpEvent(rho=0.5/noise_multiplier**2)`. Updates `dp_accounting/rdp/rdp_privacy_accountant.py` to recognize `ZCDpEvent` with `xi=0` as equivalent to a Gaussian mechanism when composing. Modifies `jax_privacy/examples/secure_noise_example.py` to use the new discrete Gaussian accounting with `RdpAccountant`. PiperOrigin-RevId: 924002229
