feat(libhttp,gateway): add admin-only WebSocket reverse proxy

libhttp v3.1:
- add ws_proxy(path, handshake) API with WsProxyHandshakeHandler callback
- implement full-duplex async bidirectional bridging (text+binary frames)
- support ws:// and wss:// backends with SNI, write queues for ordering
- proxy routes take priority over regular ws() routes
- 403 response on handshake rejection, graceful close propagation

gateway v0.6.0:
- add [WsProxy] config section (routes = /path=ws://backend;...)
- handshake callback verifies Token (Authorization/Cookie) is_admin=true
- non-admin / expired / missing token → 403, admin → transparent bridge
- fix LocalTime.hpp C++20 tzdb incompatibility on Apple clang (use strftime/get_time/mktime)
- update example.ini and README docs for both modules

 - **CAPTCHA 接口**：`/captcha` 生成验证码 token + 文本（内存存储，5 分钟过期，一次性使用）。
 - **邮箱验证码**：`/register/send_code` 发送 6 位验证码邮件（10 分钟有效）；注册时校验，一次性消费。

+### WebSocket 代理（`[WsProxy]` 配置的路径）
+
+握手阶段鉴权规则：
+
+1. 从 `Authorization: Bearer <token>` 头读取 Token；若缺失则回退到 `Cookie: q4_token=<token>`。
+2. RSA 验签 + 过期校验（与 HTTP 代理同样的 Token 机制）。
+3. Token payload 中必须 `is_admin=true`（即登录账号在 `Admin.users` 白名单内）。
+4. 鉴权失败 → 返回 HTTP 403 Forbidden，连接被拒绝。
+5. 鉴权通过 → 升级为 WebSocket 并透明桥接到配置的后端 ws:// 或 wss:// 地址，双向文本/二进制帧原样转发。
+
+客户端使用方式与普通 WebSocket 一致，只需携带有效管理员 Token：
+
+```javascript
+// 浏览器（同源会自动带 q4_token Cookie）
+const ws = new WebSocket("wss://qsont.me/ws/aibox");
+
+// 或显式带 Authorization（构造子协议或连接后首条消息均可，这里由网关在 Upgrade 头校验）
+```
+
+注意：WS 代理路由必须精确匹配（与 `ws()` 一致，非通配），且优先级高于 HTTP 通配 `*` 路由。

 近期变更：
 
+- `0.6.0`：WebSocket 反向代理（仅管理员）——新增 `[WsProxy]` 配置段，支持 `routes = /path=ws://host:port/target;...` 精确路径映射；握手阶段校验 Token 中 `is_admin=true`（基于 `Admin.users` 白名单），通过后双向透明桥接文本/二进制帧到后端，支持 `ws://` 和 `wss://`；后端连接错误/鉴权失败均优雅关闭。依赖 libhttp v3.1+ 的 `ws_proxy()` 接口。顺带修复 `LocalTime.hpp` 在 Apple clang 下 C++20 tzdb 不可用的编译问题（改用 `strftime`/`get_time`/`mktime`）。
 - `0.5.4`：修复邮件轰炸漏洞（审计报告 P0-1）——`/register/send_code` 强制 CAPTCHA 校验（经 captcha:8009，Token 一次性消费），新增邮箱级双窗口限流（3 次/小时 + 10 次/天）；smtp 层同步增加邮箱级长期限流兜底 + 全局熔断（`SMTP_HOURLY_LIMIT` 环境变量，默认 100 封/小时）；前端 `register.html`/`register.js` 同步接入图形验证码（复用 `/captcha/image` 代理路由，方案 A：仅在「获取验证码」时要求 CAPTCHA，注册提交不加）。
 - `0.5.3`：配合 smtp 同邮箱 60 秒发送冷却——`/register/send_code` 在 smtp 返回 `retry_after` 时按 429 透传其提示文案（其余发送失败仍用通用 500 文案，SMTP 内部错误细节不向外暴露）。
 - `0.5.2`：限流错误码统一为 429（登录原 400、注册/发码原 403，并修正 "attampts" 拼写）；登录时用户不存在不再兜底 500——空结果统一走 401，并执行 dummy PBKDF2 校验拉平时序防用户名枚举；db 查询失败消息由误名的 "Login (Update Step) Failed" 改为 "Login (Query Step) Failed"；pymsg 下游调用超时常量化（`DbC::DEFAULT_TIMEOUT`、`_TIMEOUT_CAPTCHA/_SMTP_VERIFY/_SMTP_SEND`）。

+**WebSocket Reverse Proxy**
+```cpp
+void ws_proxy(const std::string& path, WsProxyHandshakeHandler handshake);
+```
+
+The `WsProxyHandshakeHandler` is called during the HTTP Upgrade handshake. It receives the upgrade request and must return the backend WebSocket URL (`ws://host:port/path` or `wss://host:port/path`) to bridge to. Returning an empty string rejects the connection (HTTP 403 is sent to the client). Proxy routes take priority over regular `ws()` routes on the same path.
+
+Example — admin-only proxy:
+```cpp
+server.ws_proxy("/ws/admin", [](const http::request<http::string_body>& req) -> std::string {
+    if (!isAdmin(req)) return "";           // reject non-admins
+    return "ws://127.0.0.1:9000/stream";    // bridge to backend
+});
+```
+
+Features:
+- Full-duplex async bridging (text and binary frames preserved)
+- Write queues in both directions to maintain message ordering
+- Automatic SNI for wss:// backends
+- Graceful close propagation between client and backend
+- Errors during backend connect/handshake close the client connection cleanly
