feat(live): 添加可拖拽的全局 Overlay 小组件
feat(live): 添加可拖拽的全局 Overlay 小组件
- 新增 DraggableOverlayWidget，支持在屏幕上自由拖拽并自动吸附到边缘 - 实现主播视频视图展示逻辑，兼容主播和观众端的不同渲染方式 - 添加全局 Overlay 控制器 OverlayController，用于管理 overlay 的显示/隐藏状态 - 在 main.dart 中集成全局 overlay 组件，并通过 OverlayController 控制其显示 - 修改 LiveRoomPage 页面，在关闭直播间时切换 overlay 显示状态 - 更新 LiveRechargePopup 弹窗，使用 Get.back() 替代 Navigator.pop() - 移除 RoomController 中多余的分号及未使用的 import 和 dispose 逻辑ios
