feat: WS实时推送、网速双线图、按钮MD3修复、页面加载器修复 (v0.6.0)

后端:
- 新增 /api/system/ws WebSocket端点 替代HTTP轮询 (每2s推送系统+框架数据)
- 修复 uptime始终为0 (sm.start_time时间戳)
- 网络采集新增TX上行+实时网速(delta法)
- 进程内存采集 (/proc/self/status VmRSS)
- 抑制aiohttp内部WS帧日志防刷爆日志文件

前端:
- 仪表盘: HTTP轮询→WS连接+指数退避自动重连
- 实时日志: 修复onclose重连bug+批量渲染30fps+500行上限防卡死
- 网速卡片: DualLineChart双线图(下行实线/上行虚线)
- Y轴零点偏移-5% 防止零网速贴底
- 所有按钮修复MD3组合类(btn+btn-tonal+btn-sm)
- 页面加载器: 改动态script元素执行 修复onclick全局作用域问题
- emoji图标→Material Design SVG图标
- CSS去残留</style>+新增.nav-item svg约束
- 登录页输入框+标签左对齐+按钮MD3样式
- 多个版本号显示修复(去双重v前缀)
- chart.js/app.js/HTML页面统一加版本号防浏览器缓存
- .gitignore新增docs/目录
