The 'part number' command currently allows looking up a partition index only by its name.
Extend the command to support looking up the partition index via its partition UUID. Unlike names, UUIDs guarantee unique partition identification, avoiding ambiguity. The logic is updated to check if the provided string is a valid UUID before falling back to a name-based search.
