Phase 4 completion:
- Add ApprovalQueue component for managing pending approvals
- Add ExecutionResult component for displaying hand/workflow results
- Update Sidebar navigation to use unified AutomationPanel
- Replace separate 'hands' and 'workflow' tabs with single 'automation' tab
- Fix TypeScript type safety issues with unknown types in JSX expressions
