test(gateway): 黑盒测试重写 34 断言 + v0.8.0 增量审计闭环文档

- tests/blackbox/test_gateway.py 重写为 6 段 34 断言(输入校验/whoami+admin.verify/
  captcha-image 代理/路径遍历矩阵/限流随机XFF隔离/CORS+脱敏回归),实测 32 passed/2 skipped
- helpers.py 新增 random_xff/assert_no_internal_leak/db_execute
- docs/security/gateway_SECURITY_AUDIT_20260809.md:A1-A8 增量复审(已全部修复)
- docs/reports/libhttp_remote_addr_dev_doc.md:A4 根治方案(X-Remote-Addr 可信头注入)
- docs/INDEX.md:security 29 篇/reports 12 篇同步

gateway 黑盒用户模拟测试 — 注册 → 登录 → Token → 代理转发。
gateway 黑盒用户模拟测试(v2 — 对齐 gateway v0.8.0 契约)
用户旅程:
1. 注册新账号(含密码强度校验、邮箱格式校验)
2. 登录获取 Token
3. Token 用于代理访问后端服务
4. 重复注册(应失败)
5. 错误密码登录(应失败)
6. 无效 Token 代理(应拒绝)
7. 密码强度不足(应拒绝)
8. 邮箱格式错误(应拒绝)
覆盖范围(P0,无需测试钩子):
A. 输入校验与错误语义(v0.8.0 新契约:/login 强制 CAPTCHA、/register 强制 email_code)
B. /whoami 与 /admin/verify(fail-closed 契约)
C. /captcha/image 代理路由(captcha2 在线时)
D. 反向代理与路径安全(路径遍历矩阵,含 URL 编码变体)
E. 速率限制(随机 XFF 隔离限流桶,避免用例互斥)
F. CORS 预检现状固化 + 错误响应脱敏回归(P0-2/P0-3)
已知待修复缺陷(断言目标行为,gateway 修复前会 FAIL):
- A3: 缺失 JSON 字段 → 当前 500,应为 400(场景 A5/A8)
- A2: 白名单外 Target-Url → 当前 500,应为 403(需有效 Token 才能触达,待测试钩子)
认证 happy path(注册/登录/Token 生命周期/Cookie/jti 吊销/refresh)依赖
captcha2/smtp 测试模式(固定验证码答案钩子),落地前黑盒无法覆盖(P1 清单)。
依赖说明:
- gateway 必须运行,否则全部 SKIP
- captcha2 (pymsg:8009) 不在线时 C/E5 段 SKIP(其余用例不受影响)
- static (:9200) 不在线时 D3 段 SKIP
- smtp 不在线不影响本文件(相关用例均为 fail-closed 400 路径)
