feat(phase2): complete P1 tasks - Channels, Triggers, Skills CRUD and UI enhancements

Phase 2 P1 Tasks Completed:

API Layer (gateway-client.ts, gatewayStore.ts):
- Add Channels CRUD: getChannel, createChannel, updateChannel, deleteChannel
- Add Triggers CRUD: getTrigger, createTrigger, updateTrigger, deleteTrigger
- Add Skills CRUD: getSkill, createSkill, updateSkill, deleteSkill
- Add Scheduled Tasks API: createScheduledTask, deleteScheduledTask, toggleScheduledTask
- Add loadModels action for dynamic model list

UI Components:
- ModelsAPI.tsx: Dynamic model loading from API with loading/error states
- SchedulerPanel.tsx: Full CreateJobModal with cron/interval/once scheduling
- SecurityStatus.tsx: Loading states, error handling, retry functionality
- WorkflowEditor.tsx: New workflow creation/editing modal (new file)
- WorkflowHistory.tsx: Workflow execution history viewer (new file)
- WorkflowList.tsx: Integrated editor and history access

Configuration:
- Add 4 Hands TOML configs: clip, collector, predictor, twitter

Documentation (SYSTEM_ANALYSIS.md):
- Update API coverage: 65% → 89% (53/62 endpoints)
- Update UI completion: 85% → 92%
- Mark Phase 2 P1 tasks as completed
- Update technical debt cleanup status
