Charlie Marsh 6b9a5592a6 Avoid cloning Responses WebSocket payloads (#34381) ...

## Why

Building a Responses WebSocket request copied the model, instructions, input
history, tools, and other request settings into a second payload before
serialization.

## What changed

- Make `ResponseCreateWsRequest` borrow shared fields from
  `ResponsesApiRequest`.
- Keep only WebSocket-specific fields owned, and allocate a separate input
  vector only for incremental continuations.
- Restore response item IDs after preparing a full request so the request
  retained for continuation matching keeps its original state.

## Testing

Update the serialization test to verify that the borrowed WebSocket request
produces the same wire payload as the Responses API request plus its
WebSocket-specific fields.
