fix(codex): auto-sync API key from auth.json to form field

- Add useEffect to automatically extract and sync OPENAI_API_KEY from codexAuth to codexApiKey state
- Fix issue where API key wasn't populated in form after applying configuration wizard
- Optimize handleCodexApiKeyChange to trim input upfront
- Move getCodexAuthApiKey function closer to usage for better code organization
- Remove redundant dependency from useEffect dependency array
