Update first-boot.sh and associated scripts to transition from KDE Plasma to rpd-labwc for the Chromium kiosk setup. Modify package installations, LightDM session configurations, and one-shot scripts for wallpaper and rotation to support Wayland. Implement boot order configuration for network-first provisioning. Enhance logging and error handling throughout the scripts.
