feat: nhắc gia hạn QR theo dịch vụ, failover server hosting, CCCD admin, log cấp phát dịch vụ

- Mail campaign: mẫu nhắc gia hạn thanh toán QR, chọn dịch vụ + chu kỳ từng dòng (renewal_services) - Hosting: nhiều server Plesk cho một gói (service_plan_servers), chuyển server khi server chết - Admin xem/sửa giấy tờ định danh khách, tuỳ chọn gia hạn cho khách, nhật ký cấp phát dịch vụ - Đánh dấu mẫu email dịch vụ là non-marketing Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
