fix: 修复客户评价模糊 + 工作流程卡片溢出

🐛 HomeTestimonials:
- 移除 blur 滤镜，卡片不再模糊
- 添加触摸支持（touchstart/touchmove/touchend）
- 降低拖拽阈值（100px → 50px），更灵敏
- 加快切换动画（0.8s → 0.5s）
- 添加 select-none 防止拖拽选中文本
- 鼠标样式：grab / grabbing

🐛 HomeProcess:
- 卡片宽度缩小（280/320px → 240/280px）
- 编号圆圈缩小（20/24 → 16/20）
- 图标容器缩小
- 内边距缩小（p-6/8 → p-5/6）
- 防止最后一张卡片被遮挡
