fix(display): 隐藏调试标识 + 积分榜显示单位 logo

- TopBar 的「实例 N · 屏 N」只在该窗口确实处于调试态时渲染：非 windowed（kiosk）不显示，
  窗口化下按 F11 全屏也不显示（同时监听 fullscreenchange，与 App.vue 口径一致）
- 积分榜与团体奖牌榜的队名左侧渲染单位 logo：数据本来就下发了（dto/standings.go 的
  LogoPath），只是页面没画。图标 1em 随行字号浮动、object-fit:contain，行高不会被撑开；
  无 logo 不占位，加载失败 visibility:hidden 保留占位避免队名跳动，@load 会复原
- resolveAssetUrl（路径归一化）从 admin 目录收敛到 web/src/shared/asset.ts，
  管理端与大屏共用一份；原 image-path 测试随之迁到 shared/tests

未做（需服务端 DTO 支持，本次未授权）：分项成绩页与个人榜的单位列同样没有 logoPath 字段，
所以那两个页面仍无法显示单位 logo。

自检：vue-tsc + pnpm build 通过；前端 node --test 69/69。
