feat(ui): Phase 8 UI/UX optimization and system documentation update

## Sidebar Enhancement
- Change tabs to icon + small label layout for better space utilization
- Add Teams tab with team collaboration entry point

## Settings Page Improvements
- Connect theme toggle to gatewayStore.saveQuickConfig for persistence
- Remove OpenFang backend download section, simplify UI
- Add time range filter to UsageStats (7d/30d/all)
- Add stat cards with icons (sessions, messages, input/output tokens)
- Add token usage overview bar chart
- Add 8 ZCLAW system skill definitions with categories

## Bug Fixes
- Fix ChannelList duplicate content with deduplication logic
- Integrate CreateTriggerModal in TriggersPanel
- Add independent SecurityStatusPanel with 12 default enabled layers
- Change workflow view to use SchedulerPanel as unified entry

## New Components
- CreateTriggerModal: Event trigger creation modal
- HandApprovalModal: Hand approval workflow dialog
- HandParamsForm: Enhanced Hand parameter form
- SecurityLayersPanel: 16-layer security status display

## Architecture
- Add TOML config parsing support (toml-utils.ts, config-parser.ts)
- Add request timeout and retry mechanism (request-helper.ts)
- Add secure token storage (secure-storage.ts, secure_storage.rs)

## Tests
- Add unit tests for config-parser, toml-utils, request-helper
- Add team-client and teamStore tests

## Documentation
- Update SYSTEM_ANALYSIS.md with Phase 8 completion
- UI completion: 100% (30/30 components)
- API coverage: 93% (63/68 endpoints)
