fix(xai-oauth): recover from prelude SSE errors, gate reasoning replay, surface entitlement 403s

Browse source 
Original commit 31ba2b0cb by Teknium targeted run_codex_stream() at
its pre-refactor location in run_agent.py. Re-applied:

  - Prelude error retry/fallback → agent/codex_runtime.py (in
    run_codex_stream where the body now lives)
  - _decorate_xai_entitlement_error helper + _summarize_api_error
    wrapping → run_agent.py (these methods remained on AIAgent
    as @staticmethod's; cherry-pick applied them cleanly)

The xai-oauth provider gate, encrypted_content drop on replay, etc.
landed in agent/codex_responses_adapter.py via the prior merge from main.

Closes #8133, #14634

# ``_summarize_api_error`` can then translate into a useful
# user-facing line. Treat ``response.created`` prelude
# errors the same way we already treat ``response.completed``
