fix: remove folder icons, add single run for maintenance, fix batch 400

- Remove AddToFolderMenu from grid/list/table library views (folders removed)
- Add single "Run" button to MaintenanceFlowDetailPage alongside Batch Launch
- Change seed script to publish maintenance flows (batch rejects drafts)
