feat(automation): implement unified automation system with Hands and Workflows

Phase 1 - Core Fixes:
- Fix parameter passing in HandsPanel (params now passed to triggerHand)
- Migrate HandsPanel from useGatewayStore to useHandStore
- Add type adapters and category mapping for 7 Hands
- Create useAutomationEvents hook for WebSocket event handling

Phase 2 - UI Components:
- Create AutomationPanel as unified entry point
- Create AutomationCard with grid/list view support
- Create AutomationFilters with category tabs and search
- Create BatchActionBar for batch operations

Phase 3 - Advanced Features:
- Create ScheduleEditor with visual scheduling (no cron syntax)
- Support frequency: once, daily, weekly, monthly, custom
- Add timezone selection and end date options

Technical Details:
- AutomationItem type unifies Hand and Workflow
- CategoryType: research, data, automation, communication, content, productivity
- ScheduleInfo interface for scheduling configuration
- WebSocket events: hand, workflow, approval
