Refactor health check functionality in POE project. Removed readiness endpoint from health_check.py and improved error handling for sensor status retrieval. Updated logging to reduce noise and adjusted health check server startup process in main.py. Modified Nomad job configuration for network mode and resource allocation, enhancing overall system performance and stability.
