joeflorencio-openai 9695e71519 Add turn-scoped settings updates to the app server (#40656)
## What changed

- Add the experimental `turn/settings/update` method for changing `model`,
  `effort`, `summary`, and `serviceTier` on a specific live turn without
  changing future turns.
- Report whether the update was applied or the target turn was unavailable,
  and reject unsupported fields, disabled feature use, unsafe model changes,
  and direct updates to parent-owned subagents.
- Document the method's feature requirements, null handling, and limits.

## Testing

- Cover current-turn and future-turn isolation, rejected and unavailable
  targets, feature and capability gates, saved threads, and subagent ownership.
