[CLAUDE] PE Panel 3: bỏ phase cards + render flow workflow V2 thực tế

User feedback: "bỏ luôn cái quy trình phía trên đi nhé, vì nó là trạng
thái rồi (đã có badge), update cái flow quy trình mới vào bên panel 3
đang đến ai".

BE — ApprovalFlow DTO mới (full snapshot Bước → Cấp → NV với Status):
- PurchaseEvaluationApprovalFlowDto { CurrentStepIndex, CurrentLevelOrder,
  Steps[] }
- PurchaseEvaluationApprovalFlowStepDto { Order, Name, DepartmentId/Name,
  Status, Levels[] }
- PurchaseEvaluationApprovalFlowLevelDto { Order, Name, Approvers[], Status }
- Status: "Done" | "Current" | "Pending"

Handler GetById compute Status logic:
  - Phase=DaDuyet  → tất cả Steps/Levels "Done"
  - Phase=Nháp/Trả lại/Từ chối → tất cả "Pending"
  - Phase=ChoDuyet:
    * Step.Index < currentIdx          → all Levels "Done"
    * Step.Index == currentIdx:
        Level.Order < currentLevelOrder → "Done"
        Level.Order == currentLevelOrder → "Current"
        Level.Order > currentLevelOrder → "Pending"
    * Step.Index > currentIdx           → all "Pending"
- Load Approvers info (FullName + Email) qua UserManager batch query

FE (cả 2 app mirror):
- types/purchaseEvaluation.ts: +PeApprovalFlow + Step + Level + Status union
  PeDetail.approvalFlow optional
- PeWorkflowPanel:
  * BỎ phase cards section (4 ô Nháp/TraLai/ChoDuyet/DaDuyet) — đã
    duplicate với status badge ở header
  * Header mới: "Quy trình duyệt" + Code + Version + Name workflow pin
  * Render Flow vertical: Bước (icon ✓/●/○) → border + bg theo status
    + dept badge → list Cấp (icon nhỏ) với label "đang chờ" / "đã
    duyệt" + tên NV duyệt
  * Phiếu V1 legacy (no flow): show note "dùng quy trình cũ — không
    khả dụng chi tiết"
  * Bỏ helper isPastPhase() (orphan sau khi xóa cards)

Verify: BE build 0 error · 2 FE builds OK.

Test eoffice:
1. Mở phiếu V2 đang ChoDuyet → thấy flow Bước 1 (Phòng A):
   ✓ Cấp 1 NV X (đã duyệt)
   ● Cấp 2 NV Y (đang chờ)  ← highlight
   ○ Cấp 3 NV Z (chưa)
2. Phase=DaDuyet → all Steps/Levels green ✓
3. Phase=Nháp/TraLai → all greyed ○
4. V1 legacy → fallback note
