[CLAUDE] FE: Admin CatalogsPage CRUD + Details form datalist autocomplete

## fe-admin

### CatalogsPage.tsx (mới)

1 page generic CRUD cho 4 master catalogs (units / materials / services /
work-items). Dispatch theo URL param :kind:
- /master/catalogs (redirect units)
- /master/catalogs/:kind (units|materials|services|work-items)

Sub-tabs ở top chuyển nhanh giữa 4 kind. Mỗi kind có FIELDS_BY_TYPE config
riêng (3-7 field). Form dialog nested với input/textarea/checkbox theo type.

### Layout.tsx + App.tsx

- resolvePath thêm 4 CatalogXxx → /master/catalogs/{kind}
- Route /master/catalogs/:kind → CatalogsPage

## fe-user + fe-admin (mirror)

### ContractDetailsTab.tsx

Datalist autocomplete cho Add row form:
- Fetch 4 catalogs via TanStack Query (cache shared key 'catalogs')
- Mỗi field config thêm optional `datalist` + `datalistField` ('code'|'name')
- HTML5 <datalist> render options theo type:
  - ThauPhu: hangMuc → work-items, donViTinh → units
  - GiaoKhoan: maCongViec/tenCongViec → work-items, donViTinh → units
  - NhaCungCap/MuaBan: maSP/tenSP → materials, donViTinh → units
  - DichVu: maDichVu/tenDichVu → services, donViTinh → units
  - NguyenTacNcc: tenSP → materials, donViTinh → units
  - NguyenTacDv: tenDichVu → services, donViTinh → units

Smart-fill (handleFieldChange):
- User pick value khớp catalog → autofill sibling fields cùng catalog:
  - Field name 'maXxx' → fill code; 'tenXxx'/'hangMuc' → fill name
  - donViTinh nếu chưa có giá trị → fill từ defaultUnit của catalog item

Vẫn cho user gõ tự do (free text) — datalist chỉ là suggestion.

## Build

- fe-user: tsc + vite pass (5.69s)
- fe-admin: tsc + vite pass (633ms + 15.84s lúc test CatalogsPage lần đầu)
