[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.

 3. **Ý kiến 4 phòng ban** (Phê duyệt / P.CCM / P.MuaHàng / SM-PM) — Excel form có, entity chưa map. Cần design: 4 text field + signoff date, hoặc dùng Approvals với role-kind.
