feat: 新增静态文章模块并支持 NFC 链接分发

- 新增 Article 数据模型 + 迁移（title/subtitle/body/coverImage/caption）
- 后端：公共 /api/articles 查询接口 + 管理端 CRUD/上传/二维码
- 前端：移动端 /article/:id 阅读页（Playfair + 纸张肌理 + 首行缩进）
- Admin：新增文章管理三页（列表/表单/二维码）与侧栏入口
- 导入 6 篇点位解说词：朝天宫/七家湾/运渎/打钉巷/绒庄街/熙南里
- Admin 二维码页增加「复制链接（写入 NFC）」按钮
- 落地页步骤文案从扫码改为 NFC 触碰
- Dockerfile + entrypoint 增加 articles 图片回灌
- 修复 deploy-stamp skill 构建轮询卡住（pgrep 模式错误）
