keith thornhill bf7804c254 Add acknowledged user message submission to core (#36385) ...

## What changed

- Add `CodexThread::submit_user_input_and_wait_for_admission` and export the
  `UserMessageAdmission` result through `codex-core-api`.
- Resolve submissions only after they start a new turn or steer the active
  turn, returning the accepting turn ID in either case.
- Return errors for invalid operations, rejected thread settings, and session
  termination instead of leaving admission waiters unresolved.

## Testing

Add integration coverage for concurrent start-and-steer submissions, settings
rejection and recovery, non-user operations, and submission after shutdown.
