fix(mini-program): 修复 logo.svg 500 错误和编译问题

问题:
- SVG 文件使用 filter 和 style 属性导致小程序编译错误
- 错误信息：ReferenceError: $1 is not defined

修复:
1. 简化 SVG 文件，移除 filter 和 style 属性
   - 移除 filter (feGaussianBlur, feMerge)
   - 移除 style 属性，改用直接属性 (stop-color 替代 style="stop-color:xxx")
   - 移除 filter="url(#glow)" 引用

2. 恢复 vite.config.js 的 publicDir 配置
   - publicDir 指向 mini-program/static 目录
   - SVG 文件编译到输出目录根位置

3. 更新图片引用路径
   - splash/index.vue: /static/logo.svg
   - main/index.vue: /static/logo.svg

效果:
- logo.svg 正确编译到 unpackage/dist/dev/mp-weixin/logo.svg
- 不再出现 $1 is not defined 错误
- 小程序正常加载 logo 图片
