fix: sync openai-codex pool entry from ~/.codex/auth.json on exhaustion (#5610)

Browse Source 
OpenAI OAuth refresh tokens are single-use and rotate on every refresh.
When the Codex CLI (or another Hermes profile) refreshes its token, the
pool entry's refresh_token becomes stale. Subsequent refresh attempts
fail with invalid_grant, and the entry enters a 24-hour exhaustion
cooldown with no recovery path.

This mirrors the existing _sync_anthropic_entry_from_credentials_file()
pattern: when an openai-codex entry is exhausted, compare its
refresh_token against ~/.codex/auth.json and sync the fresh pair if
they differ.

Fixes the common scenario where users run 'codex login' to refresh
their token externally and Hermes never picks it up.
