fix(player): restore muted state when re-entering player page

修复了一个问题：点击静音按钮后退出播放页面，再次进入时虽然显示静音图标，但实际播放有声音。

根本原因：
- PlayerOrchestrator 在连接 video 控制器时，只同步了 currentTime、playbackRate 和 volume
- 缺少对 muted 状态的同步，导致 video 元素的 muted 属性未从 store 恢复

修复内容：
- 在 PlaybackContext 接口中添加 muted 字段
- 在 PlayerOrchestrator 初始化和连接时同步 muted 状态
- 在 usePlayerEngine 中从 store 读取 muted 并传递给 orchestrator
- 更新所有测试文件中的 createMockContext 函数以包含 muted 字段

影响范围：
- src/renderer/src/pages/player/engine/intent/types.ts
- src/renderer/src/pages/player/engine/PlayerOrchestrator.ts
- src/renderer/src/pages/player/hooks/usePlayerEngine.ts
- src/renderer/src/pages/player/engine/intent/__tests__/*.test.ts
