Refactor build script for custom ISO creation and update hardware configuration

- Replaced OS-specific build method with a custom ISO builder in the build-for-hardware.sh script.
- Updated output file naming to reflect the correct Alpine version in the build process.
- Adjusted build dates in hardware configuration files for HP ProDesk, merged, and Start9 Pure profiles to the latest timestamp.
