fix(codex): fix config.toml not updated after extracting common config

The handleExtract function assumed codexConfig was JSON format, but it's
actually a pure TOML string from useCodexConfigState. JSON.parse() failed
silently, causing onConfigChange not to be called.

Changes:
- Handle both pure TOML string and legacy JSON format
- Add missing i18n key for zh.json
