system-config-printer ships /etc/xdg/autostart/print-applet.desktop, so
installing it for the printer GUI also starts a ~24 MiB Python tray applet
in every session whose only job is print-job notifications. Override it
with a Hidden=true entry in config/autostart (same mechanism already used
for fcitx5 and limine-snapper-notify), so the applet no longer autostarts.
Printing and the system-config-printer GUI are unaffected.
Verified: with the override in place, systemd's xdg-autostart generator no
longer produces app-print\x2dapplet@autostart.service.
