OCPBUGS-104179:[release-4.21] Go HTTP/2: Denial of Service via malformed SETTINGS_MAX_FRAME_SIZE frame

[Pranavgarud06]

Summary

1. Fixes CVE-2026-33814 (golang.org/x/net/http2 HTTP/2 client infinite-loop DoS on SETTINGS_MAX_FRAME_SIZE=0, GO-2026-4918, CVSS 7.5) on release-4.21
2. Uses go mod edit -replace to pin golang.org/x/net to github.com/openshift-sustaining/net@v0.50.0-sec.4 (keeps go 1.24.0; the upstream fix in x/net v0.53.0 would force go 1.25.0)
3. Ran go mod tidy, go mod vendor, and verified clean build with go build ./...

Test plan

• go build ./... passes locally
• govulncheck ./... no longer reports GO-2026-4918
• CI passes
