tui: aligned voucher detail, up/down between vouchers, list sorting

The detail pads every column by display width, blanks zero amounts and
shows row texts and a Summa line. Up/Down step to the previous/next
voucher in the list order; 's' cycles the list sort (number or date,
ascending or descending, saved in tui.conf). The list fetches all pages
of voucher.list instead of stopping at 200.
