- PR #129631: fix(desktop): hand WSL external URLs to rundll32, not cmd.exe

A security vulnerability was identified where external URLs in WSL were passed to cmd.exe in a way that allowed command injection via metacharacters like \`&\`. The related items address this by switching to rundll32 and blocking dangerous inputs.
