feat(service): huỷ dịch vụ, SSL, đổi mật khẩu hosting, lịch sử thanh toán theo hình thức

- Lịch sử thanh toán hoá đơn trả thêm `method` (tự động gia hạn / số dư / admin / chuyển khoản / hoàn tiền), bỏ đuôi `(method)` khỏi ghi chú
- `DnsServer::panelUrl()` = https://<domain>/ dùng cho email cấp hosting và nút Plesk của khách
- Order item trả thêm `uuid`/`type` của dịch vụ để FE dẫn tới trang quản lý
- Yêu cầu huỷ dịch vụ, chứng chỉ SSL, lịch sử gia hạn, đổi mật khẩu hosting cho khách
