feat: add CodeRabbit integration for AI-powered code reviews

This commit introduces the CodeRabbit service and its associated routes, enabling users to trigger, manage, and check the status of code reviews through a new API. Key features include:

- New routes for triggering code reviews, checking status, and stopping reviews.
- Integration with the CodeRabbit CLI for authentication and status checks.
- UI components for displaying code review results and settings management.
- Unit tests for the new code review functionality to ensure reliability.

This enhancement aims to streamline the code review process and leverage AI capabilities for improved code quality.
