• Adds HomeAZ field population to the NodeInfo CRD creation/update functionality
• Retrieves HomeAZ information from CNS client and formats it as "AZ%02d"
• Includes comprehensive test coverage for the new functionality with mocked dependencies
• Updates Docker base image versions across multiple Dockerfiles
