Optimize login form & fix nginx issue & fix oidc issue

[finovy]

优化了登录界面更美观

修复了登录界面存在横向滚动条的问题

配置项新增OIDC_BTN_NAME，支持定义OIDC登录的按钮名称

正式环境中配置了https入口，试图对接KeyCloak登录失败，mozilla_django_oidc\auth.py中redirect_uri读取了9123端口导致回调到了http入口，导致认证完成后无法跳转到https入口

修复由于X-Forwarded-Host $host:nginx_port;的配置，导致抛出错误：

不接受这几个关于 nginx 的修改, docker-compose 和 docker 打出来的镜像就是只暴露 http 协议的, 后续再用其他的反向代理再加 https 支持

如果使用其他反向代理，那么这个问题无法解决哦：

mozilla_django_oidc\auth.py中redirect_uri读取了9123端口导致回调到了http入口

我这边用的就是反向代理, 都很正常, 这个原理是反向代理携带了正确的 X-Forward-For header, django_oidc 可以正常识别到这个 header, 你可以在这个方向检查一下

[finovy]

好的，那我回滚这个PR
