feat(health-checks): implement health check IP toggling and configuration updates

- Added functionality to toggle individual IPs for services, allowing for dynamic management of IP health status.
- Enhanced the health check configuration in the UI, enabling users to set parameters directly from the settings page.
- Updated service views to include IP health tracking, improving visibility into the status of each IP associated with a service.
- Refactored relevant components to support the new IP toggling feature, ensuring a seamless user experience.

This commit significantly enhances the health management capabilities of services, providing users with more control over IP configurations and health monitoring.
