feat: enhance CodexUsageService to fetch usage data from app-server JSON-RPC API
- Implemented a new method to retrieve usage data from the Codex app-server, providing real-time data and improving reliability. - Updated the fetchUsageData method to prioritize app-server data over fallback methods. - Added detailed logging for better traceability and debugging. - Removed unused methods related to OpenAI API usage and Codex CLI requests, streamlining the service. These changes enhance the functionality and robustness of the CodexUsageService, ensuring accurate usage statistics retrieval.
