[CLAUDE] Domain+Infra+App+FE-Admin: per-ContractType nested sidebar menu

User request: mỗi loại HĐ có menu riêng với 3 action Danh sách /
Thao tác / Duyệt.

Sidebar giờ 3-level under "Hợp đồng":
  Hợp đồng (group, expandable)
  ├── HĐ Thầu phụ (sub-group)
  │   ├── Danh sách → /contracts?type=1
  │   ├── Thao tác  → /contracts/new?type=1
  │   └── Duyệt      → /contracts?type=1&pendingMe=1
  ├── HĐ Giao khoán (sub-group)
  ├── HĐ NCC / Dịch vụ / Mua bán / Nguyên tắc NCC / Nguyên tắc DV
  └── ... (7 types × 4 = 28 new menu items)

BE:
- MenuKeys.cs: ContractTypeCodes array + helpers ContractTypeGroup/
  List/Create/Pending → key format Ct_<TypeCode>[_<Action>]
- DbInitializer.SeedMenuTreeAsync: loop seeds 28 entries under Contracts
- GetMyMenuTreeQuery.BuildChildren: descendants of `Contracts` inherit
  parent permission (avoid adding 28 rows to Permissions table per role)

FE:
- Layout.tsx recursive: MenuNodeRenderer dispatches group vs leaf by
  depth; nested groups collapsed by default (top-level expanded).
  Deeper levels get smaller padding/text + left border guide.
- Pattern-based resolvePath: Ct_<Type>_<Action> → URL with query.
- Contract type code → int map (matches Domain ContractType enum).
- ContractsListPage reads ?type + ?pendingMe, filters client-side.
  Header title + description reflect active filter. "← Tất cả loại"
  quick-reset button.
- ContractCreatePage new cho admin (copy từ fe-user), pre-select type
  từ ?type URL param.
- App.tsx route /contracts/new → ContractCreatePage.

Pure navigation UX; no new permissions needed. Admin + any role with
Contracts.Read see full menu; leaves click-through to filtered views.
