✨ feat(im): 通话窗扬声器开关 + 按钮关闭态统一深色样式 + 群通话支持刷新后重新加入

- useLiveKitRoom 增加 speakerEnabled 状态 + setSpeakerEnabled；audio 元素 :muted 联动，实现扬声器实际开关
- mic / speaker / camera / 屏幕共享 4 个按钮关闭态统一 bg-white/15 深色（之前一直 bg-white 像「开」）
- speaker / camera / 屏幕共享 关闭态 icon 借用 tabler:volume-off / video-off / device-laptop-off 显斜线（ant-design 缺 muted 变体）
- RtcGroupCallBanner 修复刷新后无法重新加入：按钮文案改为「已在通话中 / 重新加入 / 加入」三态；按钮文字色锁定深色防暗色主题不可见
- RtcCallIncoming 对齐微信样式：右上角小条 + 横排（头像 / 名 / 按钮）；群聊带「通话成员」头像行
- RtcCallRunning UnoCSS 重写 + 接收 isGroup prop（去 conversationType 派生）
- RtcCallParticipantTile UnoCSS 重写 + speakerEnabled 透传静音
- 注释 / UI 文案半角省略号 → 全角……；watcher 参数 hidden → suppressTick
