feat(filelib-web): 把 /database 各页从后端 HTML 拼接迁到 SvelteKit 路由

登录页、后台外壳与六个 tab 全部成为客户端路由:
  /database/admin              登录(迁自 renderLoginPage)
  /database/dashboard          概览(迁自 renderDashboard)
  .../library .../users .../groups .../search .../settings

六个 tab 是真 URL,不再是 location.hash + display:none —— 刷新不丢
位置,链接可分享。

BrowserShell 拆成 LibraryView,加 showUserFooter:老师端 /app 显示
身份/登出页脚,后台的文件库 tab 不显示(外层已有身份区)。

bootstrap 走 /database/config 而非 /database/api/login-info:后者由
teacherApp 在 silo org 查找成功后才注册,前者无条件注册,登录页在
org 未就绪时也必须能拿到配置。

后端拥有的链接(OAuth、DEV 一键登录)标 data-sveltekit-reload,
否则被客户端路由拦下。
