Booking mode
A booking mode decides how a booking is shaped — an arbitrary slot of time, a half-day unit, a full day, or an overnight block.
Syndik8 currently ships one mode: time-slot. The author picks an explicit start and end time and the booking covers exactly that range. The other modes (half-day, full-day, nightly) were scoped but deferred — they are not in the code.
Because only one mode is shipped, there is no UI control for picking a mode — the create-booking dialog just asks for start and end times.
