dispatchSchedule guarded status, Djibouti departure rules, locomotives and
wagons — but never checked the cargo. A train could be dispatched while the
bookings allocated to it sat received in the warehouse, silently leaving them
behind. Dispatch now refuses when an allocated booking has warehouse inventory
in RECEIVED/STORED/READY_FOR_LOADING, naming the bookings and pointing at the
two ways out: load them, or drop the wagon allocation so they ride a later
train. Bookings with no inventory at all are not blocked — allocating a wagon
before the goods arrive is normal planning.
Also drops RESERVED from the Load-to-Train filters: reserved stock is not
awaiting loading.
The sched_bookings CTE moves to common/schedule-bookings.sql so the warehouse
loading queue and this dispatch guard resolve a train's bookings identically —
if they drift, a train departs leaving cargo the warehouse still expects to load.

The Load-to-Train queue was permanently empty for real traffic. loadableTrains()
and trainLoadableItems() gated on freight.train_schedule_bookings, but nothing in
the application writes that table — only the demo seeders do. Real wagon
allocation writes wagon_booking_allocations, reached via
train_schedules -> train_sets -> train_set_wagons, so an allocated export booking
never satisfied the EXISTS gate and no train ever appeared.
Both queries now resolve a schedule's bookings through a shared sched_bookings
CTE that unions the wagon-allocation chain with train_schedule_bookings, so real
allocations show up and the seeded demo scenarios keep working. The panel already
groups the returned rows by booking with their containers, so the queue now lists
the train, its bookings and their containers for selection.
Export flow this serves: booked -> paid -> received at the warehouse (first-mile
or self-haul) -> GRN -> loaded onto the wagons allocated to the booking.
