[CLAUDE] FE-Admin+Domain+Infra+App: Workflows tab → sidebar menu items

User request: 7 tab trong /system/workflows thành menu items riêng.

Domain:
- MenuKeys.WorkflowTypeLeaf(code) helper — `Wf_<TypeCode>` pattern

Infrastructure (DbInitializer):
- Seed 7 leaves dưới Workflows group (order 95..101), label matches
  ContractType (HĐ Thầu phụ / Giao khoán / NCC / Dịch vụ / Mua bán /
  Nguyên tắc NCC / Nguyên tắc Dịch vụ). Idempotent.

Application (GetMyMenuTreeQuery):
- Generalized inherit-perm logic: descendants of Contracts AND Workflows
  inherit parent CanRead flag. Single Workflows.Read grant → all 7
  Wf_* leaves visible; no per-leaf permission rows needed.

FE Layout (admin):
- resolvePath: Wf_<Code> → /system/workflows/<code>. Ct_* still hidden
  on admin side.

FE App.tsx:
- New route /system/workflows/:typeCode?

FE WorkflowsPage:
- Removed horizontal tab bar; type selection now comes từ URL param.
- Landing view (no param): 3-col grid card per type với active version
  badge — so admin có visual overview khi click top-level Workflows
  group without selecting a type.
- TYPE_CODE_TO_INT map drives URL→int conversion.

Result: click `Quy trình HĐ > HĐ Mua bán` trong sidebar → opens
/system/workflows/MuaBan directly với designer scoped.
