docs(homepage): 精致打磨 polish pass

统一缓动曲线(cubic-bezier)与微交互质感:
- 分隔线精致化:扫描线/遥测顶线两端渐隐
- 刻度标尺主次韵律:每5格主刻度+普通次刻度双层
- HUD读数精致化:grid布局+左侧刻度点+tabular-nums+状态点
- 登记表hover升级:右移4px+标题金色+发光状态条
- 信号条hover更丝滑:位移8px+箭头发光+缓动曲线
- CTA按钮spring动效+金色阴影+active按压反馈
- 标题脉冲更柔和
- 无障碍:focus-visible金色外发光环
- reduced-motion完整降级,移动端优化
