AWS code-library documentation change

Service: code-library · 2025-07-16 · Documentation low

File: code-library/latest/ug/controltower_example_controltower_EnableBaseline_section.md

Summary

Added .NET SDK v4 code example for EnableBaseline API with parameter documentation, error handling, and operation status polling

Security assessment

The change adds documentation for enabling security baselines (a security feature) but does not address a specific vulnerability. The example demonstrates proper implementation of security controls through baseline management.
