test(medications): reach the actions of moved handler bodies in the activity inventory

The inventory reads a delegated route and its direct imports. With the medication handlers moved into lib/medications, the lifecycle reconciliation a dose write files was two levels from its route and dropped out of the walk. A route's handler-body modules now count at the route's own level, listed in one map whose every entry must be a direct import of its route.
