    .SYNOPSIS
    Applies light or dark theme colors to a WPF window's resource dictionary.

    .DESCRIPTION
    Iterates over a predefined set of theme color categories and
    populates the window's Resources with SolidColorBrush entries keyed by
    category and resource name (e.g. "AppAccentColor"). Additionally loads and
    merges shared XAML styles from the script's SharedStylesSchema path if
    available.

    .PARAMETER window
    The WPF Window whose resource dictionary will be populated.

    .PARAMETER usesDarkMode
    When $true, dark theme colors are applied; when $false, light theme colors.

    .EXAMPLE
    SetWindowThemeResources -window $MainWindow -usesDarkMode $true

    .EXAMPLE
    SetWindowThemeResources -window $Dialog -usesDarkMode $false
