feat(video): 实现基于视频流播放WebSocket的FLV功能
- 修改了Java后端代码，将视频转码服务从HLS改为FLV格式输出 - 删除了原有的HLS相关控制器和转码逻辑 - 新增了VideoWebSocketServer和VideoServerPool类来管理WebSocket连接和视频流传输- 更新了前端Vue组件，使用flv.js替代hls.js来播放视频流- 增加了WebSocket通信机制，通过二进制数据传输FLV视频流 - 移除了旧的转码状态检查和控制逻辑 - 优化了FFmpeg命令参数以适配FLV流媒体传输 - 添加了WebSocket服务器启动配置，并集成到应用启动流程中dev_flv
