feat: Phase C 完成 — ModelRouter 风格 UI 重设计 + 模拟 frps 测试 + lastSync 修复 + 集群作坊搭建

- 主题: sakura×frost 玻璃拟态 (theme.css) + SCSS 变量重映射
- 侧栏: 玻璃侧栏 246px + 渐变品牌区 + 面包屑导航
- 状态页: 玻璃 KPI 卡 + 远程节点/本地服务卡片网格
- 集群页: 英雄玻璃卡 + 横向环拓扑链 + 待办命令/活跃拓扑/日志区
- 令牌环: 新增 lastSync 上次同步时间替代周期计数
- 模拟 frps: frps2/frps3 容器 + test-forward.sh 全链路验证脚本
- 修复: BinaryPath 空导致 worker 不启动, 撤销仅撤第一个 link, 任务复活风暴 (published 追踪)
