feat: enhance Codex authentication and API key management

- Introduced a new method to check Codex authentication status, allowing for better handling of API keys and OAuth tokens.
- Updated API key management to include OpenAI, enabling users to manage their keys more effectively.
- Enhanced the CodexProvider to support session ID tracking and deduplication of text blocks in assistant messages.
- Improved error handling and logging in authentication routes, providing clearer feedback to users.

These changes improve the overall user experience and security of the Codex integration, ensuring smoother authentication processes and better management of API keys.
