function Resolve-SkuPrice {
    <#
    .SYNOPSIS
        Resolves a SKU GUID to its friendly name, part number, and monthly list price.
    .DESCRIPTION
        Looks the SKU up in the loaded price-list hashtable. Unknown SKUs return a record
        with the raw GUID as the name and a zero price so they are surfaced (counted, flagged
        "price unknown") rather than silently dropped from the report.
