Scancode.io startup fails

使用列出的 git、make envfile、docker compose build 和 docker compose up 命令重现故障。从 manage.py、scancodeio/init.py 以及 Django 的 collectstatic traceback 入手，重点关注 /var/scancodeio/static 路径和报告的权限错误。Web 容器保持运行且 Web UI 可以访问即表示完成。

Describe the bug

When running scancode.io from docker I cannot access the web ui (hangs) and I see the following in the log:
