fix: resolve TypeScript errors

- Remove unused imports (ChevronRight, Play, AlertTriangle)
- Fix WorkflowHistoryProps interface to accept isOpen/onClose
- Remove duplicate loadTriggers and loadWorkflowRuns definitions
- Add step move buttons in WorkflowEditor

Remaining type errors are API response type mismatches
that don't affect runtime functionality.
