Plot Weighted Kaplan-Meier Curves for Two Samples (Counting Process Format)

Description

Plots Kaplan-Meier survival curves for two groups using precomputed risk/event counts and survival estimates. Optionally displays confidence intervals, risk tables, median survival annotations, and statistical test results.
