feat(health-checks): enhance health check functionality and add new routes

- Introduced origin health check routes and integrated them into the application.
- Updated health check configuration to include success recovery thresholds.
- Expanded error handling with new error codes for health check failures.
- Added new service routes for managing health checks, including creation and listing.
- Improved health check service logic to track consecutive successes and failures.

This commit enhances the health check capabilities, providing better monitoring and management of service health.
