apiserver/peerproxy: avoid shadowing math/rand with local variable\n\nThis change renames a local variable named 'rand' to 'endpointIndex' to avoid shadowing the imported math/rand package in peer proxy handler when selecting a random peer endpoint. Behavior is unchanged; this improves readability and prevents future confusion.\n\n/kind cleanup\n/area apiserver\n/sig api-machinery\n\n/release-note-none\n
