Update disk-passthrough.sh

[Lifell-Adm]

This update enhances the robustness and persistence of physical disk assignment to Proxmox VMs by implementing support for /dev/by-id paths.

Changes Made:

• Added get_preferred_disk_path() function to find and select the most appropriate /dev/by-id symlink for each disk
• Modified disk detection logic to check for existing assignments using both /dev/sdX and /dev/by-id paths
• Updated disk assignment to use persistent /dev/by-id paths when available, falling back to /dev/sdX if not
• Enhanced duplicate assignment checks to prevent conflicts with both path types
• Updated script description and version to reflect the new functionality

Benefits:

• Persistence: Disk assignments remain valid across system reboots, even if disk enumeration order changes
• Robustness: Eliminates potential issues caused by /dev/sdX path changes
• Backward Compatibility: Gracefully falls back to traditional paths when /dev/by-id is unavailable
• Smart Selection: Prefers shorter, more readable /dev/by-id symlinks (model-based over UUID-based)

Files Modified:

• scripts/storage/disk-passthrough.sh: Added /dev/by-id support throughout the script

Testing:

• Verify disk assignment works with disks having /dev/by-id symlinks
• Confirm fallback to /dev/sdX paths on systems without /dev/by-id
• Test with multiple disks to ensure proper path selection
• Validate that existing assignments are correctly detected regardless of path type
