fix: 修复登录后白屏 + label标签闪屏

白屏: security.routes.js 缺少 security_settings_index 命名路由,
SidebarGroup 的 router.resolve 抛错导致所有 sidebar 组件渲染失败.
修复: 添加命名子路由指向空占位组件.

闪屏: 后端 FilterParams.Labels 用 form:"labels" 绑定,
无法解析 Chatwoot 前端的 labels[] 数组参数, label 过滤从未生效.
IntersectionObserver 检测到"还有更多数据"不断触发 loadMore,
8秒内发出 1000+ 次重复请求形成无限循环.
修复: 新增 LabelsArr []string 字段绑定 form:"labels[]",
在 handler 中合并到 Labels 字段.
