Update scripts to use dynamic username instead of hardcoded alexz

- setup-autologin-sshd.ps1: Uses $env:USERNAME, prompts for password
- setup-ssh-keys.ps1: Uses $env:USERNAME, prompts for public key
- install-nodejs.ps1: Uses $env:USERNAME in instructions
- vpn-login.js: Uses process.env.USERPROFILE for paths
