Intercity bookings never get their own train — they ride whichever import/export
train passes through their corridor — so the work is scattered across other
people's schedules and there was nowhere to see it as a whole. The per-schedule
ride-along panel answers "what can THIS train carry"; this answers "what is
happening to intercity cargo".
Purely additive: the existing ride-along panel and the schedule detail page are
untouched, and loading/unloading still happens there, where the train's position
is confirmed. This is a read-only view that points back to it.
Each row carries both ends' facility status, because a booking whose origin or
destination has no equipment can never be worked there — the operator should see
that while the train is still coming, not when the load is refused. Those
bookings are counted and called out.
New GET /train-scheduling/intercity/bookings; the type is IntercityRideAlongRow,
not IntercityBookingRow, which already means the per-schedule candidate row.

Intercity load unload
Data model — yards.has_facility, yard_facilities, facility_handling_events, resolver, seeder
The gate — intercity load/unload refused where there's no facility
GRN raised on every facility load/unload; storage only at Indode
Yards config toggle — adding a facility is now a toggle, not a code change
Which yards can handle cargo is data, not a constant — the set grows. The Yards
config screen now carries the flag, so adding a facility is a toggle rather than
a code change. Config-driven, so this is a column plus a form field.

Every facility raises a GRN — the goods changed hands, whether or not anyone
stores them. What differs is what happens next: Indode has a warehouse, so cargo
left there goes through the existing warehouse flow and accrues storage and
demurrage; Sebeta, Modjo, Adama and Dire Dawa only move cargo between train and
truck, so the handling event and its GRN are the whole record.
facility_handling_events carries that record because warehouse_inventory cannot:
its warehouse/yard/zone are NOT NULL, so a facility with equipment but no
warehouse could never have a row there. inventory_id links the storage record
when the facility does keep the cargo, which is what ties an Indode handover to
its demurrage.
generateGrnNumber moves to common/grn.util.ts so a GRN raised at a facility is
indistinguishable from one raised in a warehouse — the two live in different
tables, and a second generator would let the formats drift.
Recording is best-effort: the cargo moved regardless, so paperwork must never
fail the journey.

Intercity cargo rides a passing train and is handled at the booking's own yards,
so those yards need the equipment to do it — a train stopping somewhere is not
the same as somewhere being able to load it. Loading at an origin or unloading at
a destination without has_facility is now refused, naming the yard.
The check sits inside loadBooking/unloadBooking rather than the intercity
controller wrapper, because recording a checkpoint auto-unloads every booking
destined at that yard (autoUnloadAtYard) and would otherwise route around it.
Import/export are untouched: their cargo is handled at the route's terminal
ports, not at an arbitrary mid-corridor yard, so the gate returns early for
anything that isn't DOMESTIC.

Intercity cargo is loaded at its origin yard and unloaded at its destination, but
only some yards have the equipment. EDR's facilities are Indode, Sebeta, Modjo,
Adama and Dire Dawa — and the set grows, so it has to be data.
- yards.has_facility marks a yard as a load/unload point; the new yard_facilities
record says what it can do. Only Indode stores cargo (has_warehouse), so only it
accrues storage/demurrage — the rest just move cargo on and off the train.
- facility_handling_events records each load/unload and carries its GRN.
warehouse_inventory cannot: its warehouse/yard/zone are NOT NULL, so a facility
without a warehouse could never have a row. inventory_id links to the storage
record when there is one.
- YardFacilitiesService.facilityForYard is the single resolver the handling flows
share, so they cannot drift on what a facility is.
- The seeder flags EXISTING yards and creates none. The codes are historical and
do not read like the facility names — Indode is KALITY ("Gelan Multi Purpose
Port (Indode)") and Sebeta is LEGACY_DEST — so it maps by code. Creating fresh
INDODE/SEBETA yards would have split data that routes and bookings already
reference.
Negad is deliberately absent: NAGAD ("DCT/SGDT") is in Djibouti while
NEGAD_FY_BCC is in Ethiopia and inactive, and which one is the intercity facility
is unsettled.
No behaviour change yet — nothing reads has_facility until the gate lands.
