ref(server-utils): Share one orchestrion channel across OpenAI chat/responses/conversations (#22332)

Points the OpenAI `responses` and `conversations` APIs at the existing
`chat` channel to reduce the number of tracing channels — all three
already report the same `chat` operation with identical span handling,
so there's no behavior change.
