lt 31d6306e3b feat: 数据源统一与前端预览修复
=== 后端核心 ===
- db_helper: 统一数据库访问抽象层
- system.py API:
  * 参数绑定修复: 使用 Body(embed=True) 接收 JSON
  * 添加请求日志记录
- sync.py: 仅导出 DB→JSON(备份)

=== 合规与流水线 ===
- compliance_checker: 标签检测优化(仅检查容器,避免正文误判)
- 所有脚本(creator/collector/writer/outline/research等)统一使用数据库

=== 前端改版 ===
- topics.html:
  * 创作/优化 API 路径修正
  * 预览弹窗重设计:多平台并行加载、富文本显示、单复制按钮
  * 状态中文映射(getStatusLabel)
  * 认证检查
- 所有 HTML 静态资源路径修复(移除 /static 前缀)

=== 数据一致性 ===
- 数据库状态统一为英文(pending/review/ready/published)
- 前端显示中文化映射

已测试 A03 流水线完整通过。
