- Updated `Manager` to log additional details during refresh checks.
- Added `Refresh` method implementations for Codex, Claude, Gemini, and Qwen executors.
- Introduced OAuth-based token handling for Gemini and Qwen with support for refresh tokens.
- Updated Codex and Claude to use new internal auth services.
- Enhanced metadata structure and consistency for token storage across all executors.
- Added helper functions to log API request and response payloads in the Gin context.
- Improved `AccountInfo` to support cookie-based authentication in addition to API key and OAuth.
