Menu: flip the switches without asking for a keypress

Toggling automatic updates or notifications returned to a 'press any key'
prompt for no reason - the status block at the top of the menu already shows
the new state. cau_bad and cau_note now flag that they printed something, so
the acknowledgement only appears when there is genuinely something to read
(a failed sudoers check, a missing AUR helper) instead of after every toggle.
