fix: 修复代码块语法高亮丢失 + 语言标签注入 + 安全性增强
- 新增 cdnjs.cloudflare.com CSP 白名单，允许加载 highlight.js - 消毒策略放行 span 元素，保留 highlight.js 高亮 class - 详情页和新帖子页引入 highlight.js 库和 GitHub 主题 - 代码块语言选择器默认 text，支持 prev/next 循环切换语言 - 代码块语言标签注入兼容 data-language 和 code class 双来源 - 修复 utils.js defer 导致 common.js 执行时 getCSRFToken 未定义
