feat(health-checks): enhance health check configuration and logging

- Added new health worker URL and token fields to the AppConfig interface, allowing for Cloudflare Worker integration.
- Updated health check routes to utilize the new worker configuration, enabling dynamic health checks via Cloudflare Workers.
- Introduced a health log endpoint for services, providing detailed logs of health probe results.
- Enhanced health check service logic to support both local and Cloudflare Worker providers, improving flexibility in health monitoring.
- Updated UI components to reflect changes in health check provider settings and display relevant health information.

This commit significantly improves the health check management capabilities, allowing for better integration with Cloudflare Workers and enhanced logging features.
