feat(i18n): UI 字典串接与三页薄化——/en/ 全站落成

- op-gitea 车道：ui.ts 扩 26 键（占位 {n}/{title}/{exif} 约定），五组件
  locale prop 串接，zh 零回归（48 键/18 页实测）
- orchestrator 收尾：gallery/moments/about 三页 body 提取为
  components/pages/*Page（zh/en 薄页双路由），/en/ 全家福 21 页
- 提取工程三坑入库：HTML 注释不可进 frontmatter 模块区；搬移脚本会吃
  开栏 ---；单级页面搬二级目录后 import 全线差一层

验证: astro build 21 页 exit 0；/en/ 七类路由产物断言过；en 页
      ICP 备案保留；zh 侧文案抽查不变
