The car unit has no display of its own (the tablet app is the display),
and unified memory is better spent on the voice stack. GDM/GNOME no
longer start, a text login stays on tty1, and PulseAudio/PipeWire are
disabled for all users while ALSA stays for mic capture. Saves ~200 MB
idle; every step is a reversible disable, not a removal.
Also notes the pre-existing nightly logrotate failure from the NVIDIA
jetson-logging config.
