Fix kiosk inactivity timer for remote sessions; make Intakes table mobile-responsive

Remote sessions (customer's phone) no longer get the 45-second inactivity redirect
that requires a KioskDevice cookie — would have landed them on an error page.
Intakes staff table hides non-essential columns on small screens so the primary
customer/status/actions columns are visible without horizontal scrolling.
