feat(ca): 认证独立化 CA 模块 v1.0.0 + gateway v0.9.0 纯转发瘦身

拓扑:waf:443 → ca:8443(认证+前置转发)→ gateway:8445(仅 loopback 纯转发),
WAF upstream 不变,core/dnfs2/前端零改动。

ca v1.0.0(新模块):
- 认证资产逐字搬迁自 gateway v0.8.0(9 条认证路由、Token 双轨吊销、
  PBKDF2、限流、WS 代理鉴权、wrapperHttp、优雅关闭)
- handleForward 前置转发层:固定上游 gateway:8445;无 Target-Url 公开直转,
  有则本地验签后注入 X-Auth-User/X-Auth-Admin/Authorization(strip-then-set)
- is_special_header 新增剥离 x-auth-user/x-auth-admin;上游不可达统一 502
- confs/configs/ca.ini 新增([Upstream] gateway + UPSTREAM_GATEWAY env)

gateway v0.9.0(2470→约 560 行):
- 删除全部认证代码,退居 127.0.0.1:8445
- 启动 loopback 强制自检(非 loopback 拒绝启动)
- X-Auth-User 存在性不变量:显式 Target-Url 无该头一律 401
- gateway.ini 精简至 [Server]/[Proxy]/[Downstream db]

验收:黑盒 34 断言对 8443 原样全绿(32 passed/2 skipped,与基线一致);
探针实测伪造 X-Auth-User 经 CA 被剥离(echo 实证)、直连 8445 无头 401、
白名单外 403、gateway 宕机 CA 502。core/init.txt 加入 ca/_run.sh。

/** LogC — ca 统一日志客户端(C++ 版,对应各 Python 服务的 log_client.py)
*
* 设计要点(与 Python 版对齐):
* - 通过 pymsg TCP 调用 dbv2 execute 路由,逐条 INSERT 到 Logs 表
* - 异步非阻塞:基于 pmc::net::AsyncQueue 内存队列 + 后台线程批量推送,不拖慢业务
* - fail-safe:db 服务不可用时静默丢弃(仅 stderr 提示),绝不影响业务
* - 缓冲批量:队列满 50 条或超时 2 秒时自动 flush
* - 背压保护:队列上限 10000 条,满时丢最旧日志,防止内存无限增长
*
* 用法:
* #include "LogC.hpp"
*
* qing::LogC::instance().info("ca", "启动完成");
* qing::LogC::instance().error("ca", "数据库连接失败",
* std::nullopt, R"({"errno":2002})");
