[CLAUDE] FE: Văn phòng số foundation — shared PageHeader/KpiCard/WidgetCard + Dashboard landing (PURO · CSS Hồ sơ NS) + sync fe-admin index.css + menu Off_Dashboard

- 3 shared component PageHeader/KpiCard/WidgetCard ×2 app SHA256-identical; tái dùng token Hồ sơ NS (.app-gradient-brand/.card-accent/.icon-chip/.stat-value/.label-eyebrow + accent palette teal/violet/amberx/greenx); gotcha #66 text-white! trên gradient header.
- OfficeDashboardPage 2-cột widget kiểu PURO HomePage: Đề xuất/Đơn từ/Ticket/Phòng họp hôm nay + "Công việc của tôi" + Thao tác nhanh. Reuse query endpoint sẵn có (shared TanStack cache, KHÔNG BE/API mới), đếm client-side, loading/error/empty mỗi widget.
- Sync fe-admin/src/index.css ← fe-user (đóng drift S66-S68: heading 600→700, ink #0f172a→#0b1220, label-eyebrow slate→brand-600 + rule gotcha #66). Nay 2 app đồng bộ.
- Menu key Off_Dashboard (MenuKeys.cs const + All[] + DbInitializer seed Order 0 dưới Off) — no migration, idempotent. GIỮ ẨN non-Admin (RevokeTemporarilyHiddenModules StartsWith Off). Chưa golive.
- Wire 4-place ×2 app: App.tsx route /office/dashboard + menuKeys.ts + Layout staticMap.
- Fix KpiCard activeBorder -300 → -500 (accent palette chỉ 50/100/500/600/700 — chống "vỡ màu im lặng" Tailwind v4: border-teal-300 rơi default Tailwind, border-amberx-300 drop hẳn).
- Build PASS x2 (fe-user index-DrxDysO7 / fe-admin index-TbkadgKd) + dotnet slnx 0/0. reviewer PASS 0 blocker.
