feat: 集成 rtsp-client-android 零缓冲 RTSP 渲染，替换 ExoPlayer

- 新增本地模块 rtspclientlibrary/（拷贝自 rtsp-client-android v5.6.5 library-client-rtsp）
- RtspVideoPlayer.kt 重写：RtspSurfaceView + AndroidView，VideoCodec 枚举映射
  DecoderType.HARDWARE/SOFTWARE；指数退避自动重连（1s→30s，URL/codec 变化重置）
- 延迟统计：每 2s 轮询 statistics 输出 videoDecoderLatencyMsec/networkLatencyMsec
- 本地修复两个已知坑：CSD 参数集顺序 sps+pps+vps -> vps+sps+pps（H.265 起播黑屏根因），
  codecType 硬编码 H264 -> 按实际 MIME 标记（H.265 宽高解析）
- FrameQueue 60 -> 20 压低积压延迟；剔除 camera 依赖（删除 bitmap 渲染路径）
- app 移除 media3-exoplayer-rtsp/ui 依赖（media3-exoplayer 由库模块提供）
