// RegisterPlatformSPA 让 Go 自己吐指定 hosts 的平台后台 SPA 静态资源,
// 替代 nginx 在对应 server 块里的
//
// location ~ ^/(platform|backend|auth|api|app)/ { proxy_pass http://127.0.0.1:8081; ... }
//
// 那段反代规则(曾因宝塔重生成 vhost 被冲掉而出现 "页面 404")。
//
// 规则:
// - 仅对 hosts 列表里的 host 生效;
// - 这些前缀直接放行交给 beego Router / Static 处理,不接管:
// /platform/、/backend/、/auth/、/api/、/app/ → 业务 API
// /uploads/、/themes/ → main.go SetStaticPath 注册的静态目录
// /.well-known/ → ACME 证书验证目录
// - 其余请求从 spaDir 直接 ServeFile;
// - 文件不存在时回 index.html(SPA hash 路由 fallback)。
//
// 调用方在 router.go init() 里读 app.conf 的 platform_spa_dir / platform_spa_hosts。
// spaDir 为空或 hosts 为空则视为关闭功能,行为不变。
