🐛 fix: fix: use startxfce-community for XFCE session in livecd

XFCE now launches via startxfce-community instead of startxfce4 directly,
matching the Cinnamon pattern. Environment variables (XDG_MENU_PREFIX,
DESKTOP_SESSION, etc.) are now handled by startxfce-community instead of
being hardcoded in startbiglive. Added file cleanup and xdg-user-dirs-update
before session start, consistent with GNOME and Cinnamon paths.
