[CLAUDE] FE-Admin+FE-User: PE QuoteDialog bỏ checkbox isSelected + winner column highlight + loading overlay/spinner

User feedback 2026-05-07 (annotation):
1. Bỏ checkbox "Chọn NCC này cho hạng mục" trong QuoteDialog (consolidate winner
   selection chỉ ở Section 2.a NccSelectorRow — tránh 2 nơi pick winner).
2. Khi NCC là winner (selectedSupplierId === s.supplierId) → cell giá Section 4
   matrix ăn theo màu xanh emerald (header + cells trong column).
3. Save có delay → hiện loading spinner / overlay để user biết đang xử lý.

Implementation:
  ~ QuoteDialog (× 2 app):
    - Remove `isSelected` từ form state + UI checkbox
    - Vẫn gửi `isSelected: existing?.isSelected ?? false` lên API (giữ nguyên
      trạng thái cũ — không expose UI để tránh confusion)
    - Disable Xóa/Hủy/Lưu khi `isSaving = mut.isPending || del.isPending`
    - Button text: "Đang lưu báo giá…" / "Đang xóa…" thay "Lưu" / "Xóa"
    - Full overlay loading: absolute z-10 + bg-white/70 backdrop-blur-sm + spinner
      ring brand-600 + status text rõ ràng
  ~ ItemsTab matrix (× 2 app):
    - Column header `<th>`: thêm `isWinner` check → bg-emerald-50 + text-emerald-700
      + prefix "✓ " trước tên NCC khi winner
    - Cell `<td>`: thay `q?.isSelected` highlight → `isWinnerColumn` (entire
      column ăn theo Section 2.a winner). Cells của winner column LUÔN xanh
      bất kể quote đã nhập hay chưa (visual trace winner rõ ràng).
  ~ NccSelectorRow (× 2 app):
    - Wrap Select trong `relative` div
    - Thêm inline spinner + text "Đang chọn NCC + sync cột giá Section 4…"
      khi setWinner.isPending — báo cho user biết delay đang xử lý
