Support DISM in host initialization with MSIX PowerShell (#98)
## Summary - Import the DISM module through Windows PowerShell compatibility when `host_init.ps1` runs in MSIX-packaged PowerShell 7, retaining native DISM calls for unpackaged installs. - Stop on DISM query or installation errors instead of continuing with setup after a failed feature check. - Document the workaround and the separate PowerShell 7 remoting limitation of MSIX for the rest of the lab. Workaround for PowerShell/PowerShell#13866. ## Validation - PowerShell syntax parsed successfully, and the compatibility import exposed all four DISM commands as proxy functions locally. - User reports running the updated script on their machine; the host's feature state was not independently verified in this worktree.

For MSIX installations of PowerShell 7, the script runs DISM commands through Windows PowerShell 5.1 compatibility. The rest of the lab requires a PowerShell 7 remoting endpoint, which MSIX installations do not support.
