Captures FFU directly from host-mounted VHDX

By optimizing and mounting the VHDX directly on the host for image capture, the build process no longer needs to boot the VM into WinPE, create SMB network shares, generate temporary local accounts, or rely on complex Hyper-V switch IP configurations. This streamlines the workflow and eliminates multiple networking and permission-related points of failure.

This change also removes the need to generate and attach WinPE capture media. All related parameters (`ShareName`, `Username`, `VMHostIPAddress`, `CreateCaptureMedia`, `CleanupCaptureISO`), UI controls, capture scripts, and documentation references have been removed or updated to reflect the simplified architecture.
