Fix updater settings panel error when updater.js is blocked

Add defensive typeof checks before referencing the Updater global in
loadUpdateStatus() and checkForUpdatesManual() so the settings panel
shows a helpful message instead of crashing. Also swap script load
order so updater.js loads before settings-manager.js.
