Arrivals, departures, stayovers, and bookings-by-source were sending
request params (arrival_date_from, departure_date_from, stayover_date_from)
and reading response fields (arrival_date, booking_ref, no_nights) that
don't exist in NewBook's API — causing API errors. Switched to the real
bookings_list contract (period_from/period_to/list_type) and field names
(booking_arrival, booking_departure, reference, booking_length, etc.)
already proven working in room-planner, hvac, and kitchen's integrations.
