Fix OTB overcounting by counting distinct rooms not booking rows

Browse source 
Multiple bookings per room (early-checkout Departed + new Arrived, or
NewBook double-bookings) caused COUNT(*) to exceed total room capacity.
Switch to COUNT(DISTINCT COALESCE(room_number, newbook_id)) so each
physical room counts once regardless of how many booking rows span it.
