[CLAUDE] FE-User+FE-Admin: action buttons (Mở chi tiết + Xóa) trên row Panel 1 Thao tác

User feedback: thêm nút edit/action ở mỗi row trong list Panel 1 trang
Thao tác. Hiện absolute positioned ở góc phải-trên row, opacity-0 → 100
khi hover (group-hover). Sibling không nested để click không trigger
row select propagation.

## 2 button per row

- ⤴ ExternalLink → navigate /contracts/{id} (fullpage detail với
  Workflow + History, khác Panel 2 chỉ có Edit form)
- 🗑 Trash2 → confirm() + DELETE /contracts/{id} (soft delete,
  blocked sau DangInKy ở BE). Nếu xóa HĐ đang select → clear ?id=

## Implementation details

- pr-16 cho row button để chừa khoảng cho action group
- group-hover:opacity-100 transition (smooth fade in)
- Mutation invalidate ['my-contracts'] sau xóa thành công
- Toast success + getErrorMessage cho fail case (vd xóa HĐ đã qua DangInKy)

Build: tsc + vite pass cả 2 app (fe-user 515ms, fe-admin 937ms)
