[CLAUDE] FE-User+FE-Admin: Plan AG Chunk A+B+C — PE List tree view 2-level Project > Gói thầu

UAT feedback bro Tra Sol 2026-05-21: UI Duyệt NCC flat list "đám rừng" → tree view giống Outlook folder.

Phase 1 FE-only mirror 2 app §3.9 — KHÔNG schema mới (Phase 2 ProjectPackage defer sau UAT confirm).

Chunk A — Data transform useMemo group:
- Map<projectId, Map<normalizedGoiThau, PeListItem[]>>
- Normalize TenGoiThau: trim + toLowerCase, display raw đầu tiên trong group
- Sort: Project A-Z + gói thầu A-Z (vi locale)
- Fallback: "(Dự án đã xoá)" empty projectName + "(Chưa phân loại)" empty TenGoiThau
- Filter (pendingMe → DaGuiDuyet) áp dụng TRƯỚC group

Chunk B — UI render <details>/<summary> 2-level:
- Replace flat <ul><li> bằng nested <details> HTML native (no shadcn Accordion — gap component lib)
- 📁 Project + 📄 Gói thầu icon + count badge inline
- Chevron rotation via Tailwind group-open/proj + group-open/gt named groups
- PE card content preserve nguyên (line 209-248 unchanged)

Chunk C — Expand state localStorage persist:
- Key 'pe_list_expanded_groups' Set<string>
- Project level key: projectId; Gói thầu level key: ${projectId}::${normalizedGoiThau}
- Default empty Set (all collapse) — bro Tra Sol expect Outlook-style closed default

Verify:
- npm build fe-user PASS 0 TS err 1291.33 KB (gzip 337.00 KB) 1907 modules 16.05s
- npm build fe-admin PASS 0 TS err 1402.68 KB (gzip 357.51 KB) 1926 modules 6.86s
- KHÔNG BE change, KHÔNG Mig, KHÔNG test (UAT mode per feedback_uat_skip_verify)

Pending: Reviewer pre-commit + CICD Run #222 verify
