fix(responses): run stream failure and success hooks on the iterating loop instead of blocking it (#43270)
* fix(responses): run stream failure and success hooks on the iterating loop instead of blocking it

A dropped provider stream on native /v1/responses ran the failure logging through run_async_function from inside the async iterator, which parks the event loop thread on a helper-thread future until every failure callback returns, and never returns when a callback waits on state only that loop can advance. With a running loop the failure handlers (and the completed-stream success deployment hook) are now scheduled as tasks on it, the way chat streaming already does; the sync iterator keeps its blocking path

* fix(responses): await stream failure and success logging on the iterating loop before propagating

Keep the merge-base hook set for the native Responses stream: async_failure_handler plus the executor-thread failure_handler on failure, and the post-call success deployment hook on completion. Inside a running loop the async handler is scheduled as a task on that loop and the async iterator awaits it before re-raising, so the loop is never blocked on a foreign-loop future and the failure is attributed before the router's fallback wrapper re-enters the same logging object. The sync iterator inside a running loop keeps the task fire-and-forget with a strong reference.

* fix(responses): submit the sync failure handler only after the async one finishes
