Logging - When showing script output - note that it is signed, but don't show the signature in the logs

This is a feature request by a community member I'm capturing.

> When an actual script is needed, and that script is signed, you don't actually need to show me the text signature. Better to have output providing the signature details and indicating the script is signed, followed by the script contents with the signature parsed out (just use the AST and yank the signature from the output, especially if you already pulled the signature details separately -- the signature text itself is just useless noise).

No file, test, or entry point is identified. Start by locating the logging path that prints signed script output, then trace how the signature details and script text are produced; done means logs retain the signature details and indicate signing without printing the signature text.
