Eliminate USB requirement for WinPE PXE boot, add image upload script

- Add startnet.cmd: FlatSetupLoader.exe + Boot.tag/Media.tag eliminates
  physical USB requirement for WinPE PXE deployment
- Add Upload-Image.ps1: PowerShell script to robocopy MCL cached images
  to PXE server via SMB (Deploy, Tools, Sources)
- Add gea-shopfloor-mce image type across playbook, webapp, startnet
- Change webapp import to move (not copy) for upload sources to save disk
- Add Samba symlink following config for shared image directories
- Add Media.tag creation task in playbook for drive detection
- Update prepare-boot-tools.sh with Blancco config/initramfs patching
- Add grub-efi-amd64-bin to download-packages.sh
