Rewrites simple-install.sh to use ANSI/read-based TUI primitives
(tui_msg, tui_yesno, tui_input, tui_checklist, tui_menu) instead of
dialog, removing the dialog dependency entirely.
Updates archbaseos-guided-install.sh to invoke simple-install.sh and
drops dialog from the archiso package list; error_handler now uses the
plain read-based croc prompt unconditionally.
