v1.3.22 feat: make Hysteria2 Realm and port hopping mutually exclusive

- make Hysteria2 Realm and port hopping mutually exclusive, prompting for confirmation ([y/N], default N) in both install and -d flows
- persist deleted port-hopping NAT rules on Alpine via rc-service iptables save

v1.3.22 feat: Hysteria2 Realm 与端口跳跃互斥

- Hysteria2 Realm 与端口跳跃互斥，安装与 -d 切换前均提示确认（[y/N]，默认 N）
- Alpine 删除端口跳跃 NAT 规则后持久化（rc-service iptables save）

 2026.08.07 v1.3.20 1. Support independent (non-consecutive) ports per protocol in [sb -d], only available after installation so the install flow stays unchanged; 2. Server address accepts an IP or a domain (use DDNS for NAT VPS whose public IP changes daily); 1. [sb -d] 支持为各协议设置独立（非连续）端口，仅在安装后修改，不影响常规安装流程; 2. 服务器地址支持填写 IP 或域名（NAT VPS 公网 IP 每日变化时可用 DDNS 域名）
