OCPBUGS-80311,OCPBUGS-80312,OCPBUGS-80313: Fix CVE-2026-33186 with openshift-sustaining/grpc-go v1.71.3-sec.1 [release-4.18]

[rissh]

PR description

This change addresses CVE-2026-33186 / GHSA-p77j-4mvh-x3m3 / GO-2026-4762 in product Go modules for release-4.18 and refreshes the root vendor/ tree accordingly.

release-4.18 builds with Go 1.22 (see .ci-operator.yaml). Upstream google.golang.org/grpc v1.79.3 (the patched upstream release) requires Go 1.24, so this PR uses the OpenShift sustaining backport v1.71.3-sec.1 for Go 1.22.

For this branch, we removed the legacy grpc downgrade replace (google.golang.org/grpc => v1.63.2) and replaced it with:

replace google.golang.org/grpc => github.com/openshift-sustaining/grpc-go v1.71.3-sec.1

in the root go.mod and staging/operator-lifecycle-manager/go.mod, so the effective vendored grpc is patched.

Scope matches the release-4.19/4.20 workflow: product modules + vendor/ only (no tests-extension on this branch).
