[CLAUDE] App+FE-User+FE-Admin: Plan AG4 — bổ sung Drafter + Department vào PE List card

Anh UAT 2026-05-21: PE card danh sách thiếu người tạo + phòng ban tạo. Bổ sung 4 field
qua BE JOIN Users + Departments LEFT (cả 2 nullable theo PE entity).

BE — 4 file:
- PurchaseEvaluationDtos.cs: +4 fields DrafterUserId/DrafterName/DepartmentId/DepartmentName
- PurchaseEvaluationFeatures.cs ListHandler: JOIN Users + Departments LEFT, projection +4
- PurchaseEvaluationFeatures.cs InboxHandler: mirror JOIN + projection +4
- CreateContractFromEvaluationFeatures.cs ListApproved: mirror JOIN + projection +4

FE — 4 file × 2 app mirror:
- types/purchaseEvaluation.ts: PeListItem +4 fields
- pages/pe/PurchaseEvaluationsListPage.tsx: PE card render thêm dòng "👤 {drafterName} · {departmentName}"
  giữa Mã phiếu và Supplier. Conditional: chỉ render khi có ít nhất 1 field.

Verify:
- dotnet build clean 0 err
- dotnet test SolutionErp.slnx 111/111 PASS (58 Domain + 53 Infra) — no regression
- npm build fe-user PASS 0 TS err 1290.31 KB (gzip 336.79 KB) 1907 modules
- npm build fe-admin PASS 0 TS err 1401.66 KB (gzip 357.30 KB) 1926 modules
- 2 FE PE List file SHA256 IDENTICAL C6996194... (mirror §3.9)
- KHÔNG Mig (chỉ DTO + projection extend)

Token ~16k (close to ~14k baseline Case 2 mirror 2 app). **Pattern 19 NEW**: HTML native `<details>/<summary>` + Tailwind named groups (`group/<name>`) + localStorage Set<string> persist cho hierarchical UI when no Accordion lib available. Free open/close state native browser (Space/Enter keyboard accessible) + 0 JS state per node + serialize/deserialize Set ↔ JSON array string. Tailwind v3 named groups syntax `group/proj` parent + `group-open/proj:rotate-90` child differs from default unnamed `group` + `group-open:rotate-90` — critical when nested groups cùng level cần distinct event scope. Reusable cho future tree views: Project explorer · Dept hierarchy · Permission tree · Workflow definition step list (vs HTML5 native vs shadcn vs JS library). Anti-pattern: nested same-name `group` would inherit parent state → both rotate sync. **Pattern 5 mirror 2 app §3.9 applied 8th cumulative S20-S26** (proven reliable IDENTICAL hash check sau edit batch — recommend tooling `git diff fe-admin/X fe-user/X` after every multi-file edit batch).
