✨ feat(goods-detail): 实现商品详情页UI重构与规格选择功能

- 重构页面整体结构，包含轮播图、商品信息、规格选择、评价、详情介绍等区域
- 调整Carousel组件高度为750rpx，保持自动播放和分页指示器功能
- 实现商品信息区域样式优化，价格显示使用DIN Alternate字体和红色主题色
- 添加"起"字标识支持，应用demo商品信息区域样式
- 开发GoodsSpecSelector组件，支持规格选择和数量调整功能
- 实现底部操作栏与规格选择联动，支持加入购物车和立即购买功能
- 添加完整的商品详情页样式文件，统一页面视觉风格

🐛 fix(goods-detail): 修复库存和价格计算问题

- 修复库存判断逻辑，使用选中规格的库存而非商品总库存
- 修复价格计算问题，使用选中规格的价格而非商品基础价格
- 修复数量选择器边界值问题，确保不能选择超过库存的数量
