feat(cleaner): support selectedManagers filtering for admin cleaner execution

Admin can now pass selectedManagers to getCleanerData so material codes
are queried from MaterialsToBeDeleted by ManagerName IN (selectedManagers).
When no managers are selected, fallback to DiscreteMaterialPlanData by
orderNumbers. User behavior is unchanged. Includes updated tests and
role-based flow documentation.
