Overhaul preseed.cfg from a semi-interactive installer (prompting for
LUKS passphrase and user credentials) to a fully unattended dev/test
setup with hardcoded credentials. Enable networking and configure a
Debian sid pin to pull Hyprland, UWSM, SDDM, and foot during
late_command. Add serial console support in GRUB for headless debugging.
Also update the FSD with the "match upstream Omarchy" design principle
and bump the last-updated date.

The debconf preseed parser interprets \n in string values as literal
newlines. The printf format string had its \n converted to real newlines
before the shell saw it, causing ExecStart= to be executed as a separate
command ("Illegal number: ExecStart="). Replace the single printf with
multiple echo statements that avoid \n entirely.
