[CLAUDE] PurchaseEvaluation FE-Admin FE-User: Chunk L5 — PE list UX: ngày tạo thay SLA countdown + sort UpdatedAt DESC

Bro UAT S23 t2 yêu cầu 2 UX changes PE list:

1. Đổi "Còn N ngày Mh" (SlaTimer countdown) → "DD/MM/YYYY HH:mm" (ngày giờ tạo phiếu).
2. Sort: phiếu vừa update (Tạo / Gửi duyệt / Trả lại) đưa lên đầu, phiếu cũ phía dưới.

BE changes:
- PurchaseEvaluationListItemDto +UpdatedAt: DateTime? field (auto AuditingInterceptor refresh
  mọi SaveChanges — covers Insert/Update/Transition events natural).
- ListPurchaseEvaluationsQueryHandler sort: OrderByDescending(UpdatedAt ?? CreatedAt)
  (was: OrderByDescending(CreatedAt)).
- GetMyPurchaseEvaluationInboxQueryHandler sort: OrderByDescending(UpdatedAt ?? CreatedAt)
  (was: OrderBy(SlaDeadline ?? MaxValue) — SLA priority deprecated).
- CreateContractFromEvaluationFeatures.cs: +UpdatedAt arg trong DTO ctor (compile fix
  consumer downstream).
- Select projection 3 callsites populate UpdatedAt.

FE × 2 app (mirror rule §3.9):
- PeListItem type +updatedAt: string | null (optional — null khi phiếu chưa Update).
- PurchaseEvaluationsListPage: replace <SlaTimer deadline={p.slaDeadline} ... /> với
  Vietnamese date format "{DD/MM/YYYY HH:mm}" qua Intl.DateTimeFormat (vi-VN locale,
  full date+time options). title tooltip hiện full timestamp.
- Remove SlaTimer import (unused warning).

UpdatedAt sort logic insight: AuditingInterceptor (Infrastructure) auto-refresh
UpdatedAt mọi SaveChanges → mọi event tự nhiên (Drafter tạo / Gửi duyệt từ Workspace
/ Approver duyệt Cấp tiếp / Approver trả lại / Admin override) đều bump UpdatedAt
→ phiếu vừa action lên đầu list. Phiếu mới Insert UpdatedAt=null → fallback CreatedAt
→ vẫn lên đầu (vì CreatedAt vừa now).

Verify:
- dotnet build production projects clean (0 err, 2 pre-existing warn)
- dotnet test SolutionErp.slnx 104/104 PASS (DTO change KHÔNG impact test — tests
  don't construct ListItemDto)
- npm run build × 2 app pass clean
