fix: auto-create default user, force reboot, i915 firmware, first boot info

Critical fixes from ISO testing on .198:
- Backend auto-creates default user (password123) on first start
  so login works immediately after onboarding
- Force reboot (reboot -f) after install to avoid SquashFS errors
  when live USB is removed
- Eject USB before prompting user, not after
- Add firmware-misc-nonfree for Intel i915 GPU (suppresses dozens
  of "Possible missing firmware" warnings during initramfs update)
- First boot screen: wait up to 10s for DHCP before showing IP
- First boot screen: compact layout fits 80-col terminals
- ISOLINUX menu resolution dropped to 640x480 for universal
  VESA compatibility (was 1024x768, caused scaling on some hardware)
