[CLAUDE] PurchaseEvaluation: demo seed 4 phieu + MaPhieu atomic sequence + Pe_* perm defaults

Polish session tiep cua PE module skeleton (commit 2c6f0ca..3990066):
3 task A (MISSING in MVP) khac STATUS.md In Progress:

1. Demo PE data seed (SeedDemoPurchaseEvaluationsAsync)
   - 4 phieu varied A/B x phase: A-001 DangSoanThao (mo), A-002
     ChoCEODuyetNCC (winner+9 quotes), A-003 DaDuyet (chua tao HD,
     PaymentTerms JSON), B-001 ChoDuAn (5-step giua chung).
   - Idempotent: skip-if-[DEMO]-exists.
   - Approval history dung policy A (3-step) hoac B (5-step).

2. MaPhieu atomic sequence — Migration 13
   - Format PE/{YYYY}/{TypeLetter}/{Seq:D3} (vd PE/2026/A/001).
   - PurchaseEvaluationCodeSequence entity (Prefix PK).
   - IPurchaseEvaluationCodeGenerator + impl SERIALIZABLE
     transaction (mirror ContractCodeGenerator 1:1).
   - Replace Random.Shared trong CreatePurchaseEvaluationCommandHandler.
   - Migration AddPurchaseEvaluationCodeSequences (1 bang).

3. Pe_* permission defaults
   - SeedPurchaseEvaluationPermissionDefaultsAsync — 7 role business x 9 menu key.
   - Drafter/DeptManager/Procurement: R+C+U; CostControl/PM/Director/AuthorizedSigner: R+U.
   - DeptManager them Delete (xoa nhap).
   - Idempotent per-(roleId x menuKey).

Build: 0 error, 2 warning (pre-existing DocxRenderer).

Files: 4 new + 8 modified (1 migration + entity + generator + DI + 2 ctx + 2 features).

Resolves: STATUS.md In Progress §A — 3 item PE MISSING.

+"Chốt lại toàn bộ MD: 'rules, architech, gotcha, skill, daily, hand-off, DB,
+luồng DB ...' và làm tiếp đi nhé." → continue PE polish theo STATUS.md §🔥 In
+Progress nhóm A (chức năng MISSING trong MVP).
+
+## Tasks completed (4)
+
+### 1. Demo PE data seed — 4 phiếu varied
+
+**File:** `src/Backend/SolutionErp.Infrastructure/Persistence/DbInitializer.cs`
+
+`SeedDemoPurchaseEvaluationsAsync` — pattern mirror `SeedDemoContractsAsync`:
+
+| Phiếu | Type | Phase | Đặc điểm | Quotes |
+|---|---|---|---|---|
+| `[DEMO]-A-001` | DuyetNcc | DangSoanThao | Drafter mới mở, chưa nhập giá | 0 |

+đúng theo policy A (3-step Procurement→CCM→CEO) hoặc B (5-step
+Procurement→PM→CCM→CEO PA→CEO NCC). ApproverUserId mapping đúng role.
+
+**Resolves:** STATUS.md §🔥 A — "Demo PE data seed".
+

+- `IApplicationDbContext` + `ApplicationDbContext` thêm `PurchaseEvaluationCodeSequences` DbSet
+- `PurchaseEvaluationConfiguration` thêm `PurchaseEvaluationCodeSequenceConfiguration` (Prefix max 100)
+- `DependencyInjection` register Scoped `IPurchaseEvaluationCodeGenerator → PurchaseEvaluationCodeGenerator`
+- `PurchaseEvaluationFeatures` `CreatePurchaseEvaluationCommandHandler` constructor inject codeGen, replace `Random.Shared` với `await codeGen.GenerateAsync(entity, ct)`
+
+**Format:** `PE/{YYYY}/{TypeLetter}/{Seq:D3}` — VD `PE/2026/A/001`, `PE/2026/B/001`.
+TypeLetter = `A` (DuyetNcc) | `B` (DuyetNccPhuongAn).

+
+9 menu key per role: `PurchaseEvaluations` (root) + 2 group (`Pe_DuyetNcc`,
