fix(warehouses): Store no longer strands an import item in STORED

READY_FOR_PICKUP allows STORED (park an import item back into storage), but
STORED allowed only RESERVED / READY_FOR_LOADING - so readyForPickup() hit
assertTransition(STORED, READY_FOR_PICKUP) and threw. The item could never
return to pickup, and getNextInventoryAction returned null for an import STORED
item, leaving the row with no action at all.

- allow STORED -> READY_FOR_PICKUP
- an inspected import STORED item now advances to ready-for-pickup

readyForPickup() still rejects non-IMPORT inventory, so the new edge cannot be
reached from the export flow.
