Refactor Disk and Memory Size Formatting with Centralized Utility Function

- Extracted common size formatting logic to a new utility function `HumanSize` in utils package
- Removed duplicate size formatting code from Disk and Memory configurations
- Updated Disk and Memory modules to use the centralized size formatting utility
- Uncommented and implemented disk usage calculation in Disk configuration
- Improved code readability and maintainability by centralizing size conversion logic
