<#
.SYNOPSIS
    Sets PC identity: computer name, description, and creates C:\X9 folder structure.

.DESCRIPTION
    Renames the computer if deployment.pcName is set in config.json. Sets the
    computer description (visible in System properties and network neighborhood).
    Creates C:\X9\ directory structure with subdirectories for logs, scripts and
    assets. Copies X9 icon and creates Desktop.ini so the folder shows a custom
    icon in Explorer. Computer rename requires a restart - this step runs last
    before the final summary.

.ITEMS
    rename-computer-dle-config-deployment-pcn: Renames the computer via Rename-Computer if config.json deployment.pcName is set and differs from the current name. Rename takes effect after restart. If pcName is empty, rename is skipped and the current name is preserved.
    popis-pocitace-computer-description: Sets the computer description shown in System Properties and Network Neighborhood. Read from config.json deployment.pcDescription, default "X9 deployment". Written to HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\SrvComment.
    vytvorit-cx9-adresar: Creates C:\X9\ with subdirectories Logs\, Scripts\, Assets\. Used for deployment logs, custom per-client scripts, and client-specific configuration assets.
    cx9-vlastni-ikonka-desktop-ini: Copies X9-ikona.ico to C:\X9\ and creates Desktop.ini with IconResource entry. Sets System+Hidden attributes on Desktop.ini and ReadOnly on C:\X9\ so Explorer displays the custom folder icon.
