fix: 修复自动播放循环与暂停失效问题 (H-UI-05/H-UI-07)

- fix(player): 修复 checkPlaybackState 无限重试循环，添加最大重试次数限制 (3次)
- fix(player): 修复 handlePlayMusic 参数 isPlay 遮蔽同名 ref 导致 play/isPlay/userPlayIntent 状态不同步
- fix(player): 播放成功后清除 isFirstPlay 标记，避免暂停时被 setPlay 误判为新歌从头播放
- fix(ui): 移除 AppMenu z-index 重复声明 (H-UI-05)
- perf(ui): MiniPlayBar 进度条 hover 改用 transform: scaleY() 替代 height 变化 (H-UI-07)
