What Does This Do

NOTE: This is an experiment to see how Datadog CodeGen performs on integration issue

Add HTTP/2 headers frame handling in the Netty server response tracing handler so http.status_code is set on netty.request spans
Add a regression test covering HTTP/2 responses to ensure the status code is recorded

Motivation

HTTP/2 responses in Spring Cloud Gateway/Netty are written as Http2HeadersFrame, so server spans were missing http.status_code and surfaced as N/A

Additional Notes

Tests and formatting could not be run in this sandbox because Gradle downloads require network access
