feat: 支持按键分离事件与键盘捕获，并优化UI

- 后端与前端新增 keyAction 参数，支持按键按下/抬起独立事件，保持向下兼容
- 前端控制栏支持 pointerdown/pointerup 长按，新增键盘捕获输入框，映射浏览器按键到 Android KeyEvent
- 重构顶栏布局：用户区右置并添加在线指示器、状态文本省略，优化窄屏响应式表现
- 控制栏录制按钮组防拆行，分辨率/帧率选择器自适应收缩，全局样式增强
- 修复 AdminAuthFilter 中 doFilter 被异常捕获导致误返回 401 的问题
- 移除管理后台中用户 admin 角色及相关 UI 与 API
- 更新信令前端环境代理地址，修正路由名称大小写
