fix(polish): 上线四缺陷修复——明暗委托/灯箱常开/评论站点名/书评宋体

- 明暗切换：document 级委托（软导航换 DOM 后元素级监听全丢）；
  E2E 再抓一坑：SVGElement 非 HTMLElement 实例，守卫用 Element 基类
- 图库：#lb 无条件 display:flex 覆盖 UA 隐藏 → 灯箱"永远打开"盖全页；
  改 #lb:not([open]) 显式 none；时间戳标题清空；灯箱打磨（切换钮
  实底阴影/n/21 计数器/空标题隐藏/原图链接暗底亮蓝）
- 评论：site 'wait4x'→'wait4x.online' 对齐 Artalk 服务端（404 根因）
- 书评字体：文楷→思源宋（@fontsource 预分片）；文楷降级金句 --font-kai
- 数据：21 张照片组修正 street→landscape（迁移器收到内部组 id 的坑）
- 新增 tests/e2e.mjs：Playwright 30 项全功能 E2E

验证: node tests/e2e.mjs 30/30 PASS（含软导航后明暗切换回归项）
