[CLAUDE] FE-User: Inbox thêm section Phiếu Duyệt NCC chờ tôi

Optional polish (HANDOFF §C — "khi UAT phát sinh"). Drafter + TPB sẽ thấy
HĐ + Phiếu PE pending cùng InboxPage thay vì phải vào /purchase-evaluations
riêng.

Changes:
- useQuery thứ 2 cho /purchase-evaluations/inbox (endpoint đã sẵn)
- peRows filter theo search query (mã / tên gói thầu / project)
- Stats overdue/dueSoon đếm cả PE rows. totalValue chỉ HĐ (PE không có giá trị).
- Panel 1 chia 2 section sticky header:
  - "Hợp đồng (N)" — giữ behavior cũ, click → inline detail Panel 2
  - "Phiếu Duyệt NCC (M)" — click → navigate /purchase-evaluations/:id
    (page riêng, không inline vì PE entity shape khác Contract)
- EmptyState mới: "Không có HĐ hoặc Phiếu Duyệt NCC nào chờ"

Note: chỉ fe-user (đối tượng dùng Inbox), fe-admin có /system/inbox riêng
nếu cần — defer.

Build: fe-user pass.
