fix: 修复首页加载和动画时序问题

🐛 问题修复:
- 移除所有新板块的初始 opacity: 0 样式
- 防止新板块初始隐藏导致黑屏问题
- 确保页面加载后内容立即可见
- 修复菜单延迟出现的问题

🎨 优化调整:
- 改用 CSS class 控制动画初始状态
- ScrollTrigger 动画在滚动到对应位置时才触发
- 不影响首屏 Hero 和 Intro 的加载动画
- 保持所有板块的入场动画效果

✅ 修复的组件:
- HomeServices
- HomeAchievements
- HomeTestimonials
- HomeTechStack
- HomeProcess
- HomeUpdates
- HomeCTA
