olivier 64352817f5 Add winget repair helper and remove winget configure --enable prerequisite
Initialize-Winget.ps1 refreshes PATH, re-registers App Installer and
falls back to the provisioned package before exiting with a Store link.
All scripts that call winget now dot-source this helper instead of
failing on a missing winget.
