feat(warehouses): gate loading queues on the train's station loading window

Warehouse loading queues and the train schedule page now share one truth:
the schedule's per-yard stationWorkLogs. A booking's items aren't loadable
until "Start loading" has been clicked for their boarding yard, mirroring
the same assertStationWorkStarted check the train schedule page's own Load
button already enforces.

- LoadableTrainRow/LoadableTrain carry originStationId + stationWorkLogs.
- TrainLoadableItem carries originYardId/originYardLabel/loadingWindowStarted,
  computed from station_work_logs in the same query.
- New YardLoadingWindows component surfaces the per-yard windows on the
  loading panel; ReceiveInventoryModal and LoadToTrainPanel wire it in.
- Invalidate loadable-trains/train-loadable-items/warehouse-inventory
  queries alongside train-scheduling ones, since they render off the same
  data.

Fixes the StationWorkLogJson typo that broke the freight-api build.
