List locations where a product is available
Returns the set of warehouse locations at which this product (typically a box) is
physically stocked / available. PackPilot uses this list to filter candidate boxes by
the order’s location_id so multi-warehouse entities don’t get boxes from the wrong
warehouse assigned. When the junction is empty for a given location, PackPilot falls
back to the entity-wide box list (preserves single-location and unassigned-order
behavior).
Requires products:read scope.
