The previous startOnBoot approach booted mibook headless by default and
locked the machine out: it is WiFi-only with credentials in KWallet, so
with no desktop session NetworkManager never joins the network (no SSH),
and boot stalled on NetworkManager-wait-online with the tty1 prompt
buried under service logs.
Replace it with a NixOS specialisation that adds a separate 'terminal'
GRUB entry:
- default entry boots KDE as before (identical to baseline);
- 'terminal' entry boots multi-user.target with autologin for finn and a
'desktop' command to start SDDM on demand.
Also disable NetworkManager-wait-online so boot never stalls on the
network. Revert the kde-desktop startOnBoot option.
