refactor(utils): improve whiptail dialogs and logging utilities

- add adaptive terminal sizing for all whiptail dialogs (wt_get_size)
- add new wrapper functions: wt_checklist, wt_radiolist, wt_menu
- add safe parser wt_parse_choices to replace eval
- improve NEWT_COLORS theme with better contrast (brightgreen/brightcyan)
- add new logging functions: log_header, log_subheader, log_divider, log_box
- add spinner animation utilities for progress indication
- expand color palette with bright variants and text styles
- update 04_wizard.sh to use new whiptail wrappers
