Update Open Codex commit attribution identity

Switch the default co-author trailer from the upstream Codex identity to the
Open Codex identity, and keep the config reference/schema/docs aligned with
that default while preserving the existing feature-gated semantics.

Tests:
- cargo test -p codex-core commit_attribution
