refactor(https): 协议识别下沉到 nginx，TrustProxies 只信 X-Forwarded-Proto

- nginx 经 APP_SCHEME 环境变量(envsubst 模板)统一控制 X-Forwarded-Proto
- TrustProxies 信任内网代理但仅采信 X-Forwarded-Proto，防 Host 注入
- 移除 WebApi 中间件的硬编码强制 https
- getSchemeAndHost 优先用当前请求 scheme/host，保留非请求上下文兜底
- cmd https 切换后改用 compose up -d 重建 nginx 容器使 envsubst 生效
