站点首页此前显示的是 Dashy 上游的 logo —— index.html 里那几条
<link rel=icon href=/web-icons/favicon-*.png> 优先级高于我们的门户图标，
而扩展的 PNG 是占位图（128px 只有 9 种颜色、alpha 通道还是乱的）。
- portal/favicon.svg：纸飞机（圆角渐变底 + 白色折纸机头朝右上 + 两道尾迹），
几何收在 8..56 安全区，避免贴边被圆角裁切
- 由该 SVG 派生 favicon.ico(16/32/48)、apple-touch-icon(180)、
web-icons/favicon-{16,32,64}、扩展 icon{16,48,96,128}
- patch-index.py：删掉上游 icon link 并显式指向 /favicon.svg（幂等，
重复执行 unchanged）；上游 web-icons 那批也覆盖一份作双保险
- Dockerfile 与 zd-host.sh 都 COPY 这些图标进镜像
- 验证：nginx 沙箱实测 /favicon.svg、/web-icons/*、/apple-touch-icon.png 均 200；
16px 下人眼仍可辨识为纸飞机
- .amo-upload-uuid（web-ext 生成的 UUID）改为忽略
