feat: 创作工作台统一 + AI味检测/白标 + 移动端补全 + 合规发布闭环

- 新增创作工作台 studio.html：合并选题/内容工厂/文章管理为单一 tab 入口（iframe embed 模式）
- 新增 AI味检测模块（ai_slop API + 页面，合规软硬问题分级）
- 新增白标品牌配置（branding API + 页面 + deploy 私有化交付包）
- 发布闭环：publishing 放宽至 editor + records/mark-published 接口
- 移动端响应式补全（admin/calendar/ai-slop 表格卡片兜底）
- 修复菜单幂等播种缺陷（按 path 对齐，避免功能页孤立）
- 新增短视频脚本 shortvideo.py 与 2026 市场调研简报
