fix(clipcatctl): fix output ordering of list cmd

[james64]

Hi,

this is a fix for #1053 . Output is not stable becuase fresh instance of tokio::io::stdout is created inside for loop for ever entry. Each stdout has its dedicated worker creating a race condition. Creating single instance outside the loop solves the problem. See commentary in tokio doc. I have tested it locally and the problem is gone.

Let me know if I need to update anything 👍
