# Change: Add Resource Management UI

## Why
HIGH-006: The Resource Management module backend API exists but there is no frontend UI. Managers cannot visualize team workload distribution, making capacity planning difficult.

Issues addressed:
- HIGH-006: 資源管理模組前端 UI 未開發

## What Changes
- Create WorkloadPage.tsx with workload heatmap visualization
- Create WorkloadHeatmap.tsx component for color-coded user load display
- Create WorkloadUserDetail.tsx component for detailed task breakdown
- Add /workload route to App.tsx router
- Add navigation link in Dashboard or sidebar

## Impact
- Affected specs: resource-management

  - `frontend/src/pages/WorkloadPage.tsx` - new page
  - `frontend/src/components/WorkloadHeatmap.tsx` - new component
  - `frontend/src/components/WorkloadUserDetail.tsx` - new component
  - `frontend/src/services/workload.ts` - new API service
