Problem

Currently, Operaton returns a 404 error when accessing /health, which is commonly expected for:

• Load balancer health checks
• Monitoring systems
• Container orchestration platforms
• Uptime monitoring

Current Behavior

• GET /health returns 404 with "Whitelabel Error Page"
• Error message: "This application has no explicit mapping for /error"

Requested Feature

Add a simple health check endpoint that returns:

• HTTP 200 when application is healthy
• Basic JSON response like {"status": "UP", "timestamp": "..."}
• Optional: Include basic system info (database connectivity, version, etc.)

Use Case

We're running Operaton behind a reverse proxy and need a reliable endpoint for health monitoring in our infrastructure.

Proposed Implementation

Standard Spring Boot Actuator health endpoint or custom controller at /health
