[easy] Add health check endpoint to permission-service

[davedumto]

Summary

permission-service does not currently expose a health check endpoint, making readiness monitoring inconsistent with other services.

Requirements

• Add a GET /health endpoint returning service and dependency status
• Include database connectivity in the health check
• Add a test verifying the endpoint reports unhealthy on a dependency failure
• Wire the endpoint into the existing deployment health checks
