feat(intercity): a facility only handles the cargo its equipment can lift

Containers need a reach stacker or gantry, so only Indode, Modjo and Dire Dawa
take them. Bulk needs far less and is handled at all five facilities. Having a
facility was previously enough to load anything, so a container booking through
Sebeta or Adama would have been accepted and then had nothing to lift it.

- yard_facilities gains handles_container / handles_bulk, both defaulting true so
  a facility handles everything unless told otherwise; the seeder states the real
  capability.
- The intercity gate now refuses cargo a facility cannot lift, saying which type,
  not just "no facility". canHandleFreight keeps that rule in the resolver so
  callers cannot get it subtly wrong.
- The intercity list resolves each end against the booking's own freight type, so
  the view flags a container booking routed through a bulk-only yard while the
  train is still coming rather than when the load is refused.

Import/export untouched — the gate is still DOMESTIC-only.
