style(training/metronome): 优化中央圆 UI,移除顶部拍点指示

- 移除顶部 .beat-bar 4 个圆点指示器,界面更简洁
- 中央圆按钮重新设计:
  · "速度"标签下方居中放置纯 CSS 几何绘制的大 ▶/⏸ 图标
    (icon-play 70rpx 三角形 / icon-pause 22rpx×84rpx 双竖条),
    跨机型一致、不再依赖 emoji 字符
  · 移除"开始/暂停"文字 + 药丸样式背景,保留 icon 即可识别
  · 圆心使用更深的渐变和内/外阴影,质感更立体
  · 增加第二层 ring 错相 0.4 周期播放,呼吸感更连续
- 状态提示文案调整:"点击" → "轻点"
- 顶部 padding 收紧 60rpx → 20rpx,圆体上下居中更平衡
