    .SYNOPSIS
        Shows, updates, or hides the window-level progress indicator used by long-running
        workflows such as app management, Tweaks, AppX management, and Win11 Creator.
        It lives outside the TabControl, so it stays visible no matter which tab is active.
    .PARAMETER Visible
        Whether the indicator should be shown or hidden.
    .PARAMETER Label
        The text to display above the progress bar.
    .PARAMETER Percent
        The percentage of the progress bar that should be filled (0-100).
