重构：移除 RDP 管线并完善会话退出与串流过场

变更详情：删除 RDP 渲染管线，协议统一 Moonlight；退出三层设计与串流过场层落地 - 移除 rdp_session.*、FreeRDP 构建依赖与代码内协议概念，Moonlight 为唯一会话通道 - Ctrl+Alt+Shift+Q 退串流回列表（kiosk 兜底 + moonlight-qt 主路径）；登录页去退出按钮 - 新增 TransitionOverlay：全屏过场层盖住串流启动闪烁，进程 CPU 首帧检测后淡出 - Sunshine 写入 sw_preset=ultrafast；实测推翻 x264 瓶颈结论（21.6FPS 帽子在虚拟显示/捕获节奏，CPU≈0%） - 文档：麒麟(101/.71)/Ubuntu(102/.72) 接入信息与四件事落地记录；MEMORY 根因修正
