feat: thiết kế lại bộ lọc /di-tich + marquee cuộn liên tục (luôn bật)

- Bộ lọc cao cấp: ô tìm kiếm bo tròn full-width có nút xóa, tóm tắt số kết quả,
  3 hàng lọc có nhãn + chip kèm số đếm, tóm tắt bộ lọc đang áp dụng + xóa tất cả
- Marquee tên di tích: animation luôn bật (gỡ cổng no-preference khiến đứng yên),
  vẫn cuộn chậm nhẹ dưới reduced-motion
