A booking linked to a stop has two days to go by, its own date and the
stop's. They part when the stop is moved to another day or the trip is
shifted with "keep bookings on their dates", and the plan then listed the
booking at the stop and again in the timeline of its own day. The stop now
wins wherever both are drawn: the desktop day plan and day detail, the
phone's plan tab and day sheet, and the road trip rail on both. The
booking's date is left as it is; a stop on one of the booking's own days
changes nothing, so a rental picked up at a stop still runs across its
other days.

The desktop day panel and the phone day sheet load the day's forecast with
useDayForecast, rename the day with useDayRename, and read the day's
bookings, the stay labels and the display temperature from dayDetailModel.
