Add WiFi safeguard and apt upgrade to SpoolBuddy install script

Browse Source 
Install script now runs apt-get upgrade -y after installing system
  packages. A WiFi safeguard (APT hook + helper script) is installed
  first, backing up NetworkManager connections before dpkg and restoring
  them if wiped — prevents headless Pis from losing WiFi during upgrades.
