Kiosk intake: 45-second inactivity reset to Welcome screen

_KioskLayout inactivity timer now reads ViewBag.InactivityTimeoutMs
(defaults to 5 min). PopulateKioskViewBagFromSession sets it to 45 s
on every intake step so an abandoned form auto-returns to the waiting
screen. Welcome screen and Confirmation page are unaffected.
