…hen downloading program.

Also renamed the input parameter for clarity

Note

Low Risk
Small, localized change to download-program plumbing and input validation; main risk is minor behavior change for callers previously passing empty strings.

Overview
commandDownloadProgram(WithResponse) now consistently uses the parameter name program_name (instead of filename) across the public DashboardClient API and both G5/X implementations, including updated docs.

On the PolyScope X implementation, downloading a program now fails fast with a clear error DashboardResponse when either program_name or save_path is empty, instead of issuing the HTTP request.
