Improve boot UX: status display, faster GUI, loading spinner

- Add bee-boot-status service: shows live service status on tty1 with
  ASCII logo before getty, exits when all bee services settle
- Remove lightdm dependency on bee-preflight so GUI starts immediately
  without waiting for NVIDIA driver load
- Replace Chromium blank-page problem with /loading spinner page that
  polls /api/services and auto-redirects when services are ready; add
  "Open app now" override button; use fresh --user-data-dir=/tmp/bee-chrome
- Unify branding: add "Hardware Audit LiveCD" subtitle to GRUB menu,
  bee-boot-status (with yellow ASCII logo), and web spinner
