Phase 3+4: 共享 HTTP 客户端 + admin API + audit log

Phase 3 (httpclient): - shared Client (Timeout + MaxResponseBytes 截断) - SSRF: 16 段私网 CIDR (含 169.254/::ffff:0:0/96 IPv4-mapped) + hostname allowlist (精确/后缀/*. 通配) + scheme 校验 (仅 http/https) - auth 适配器: none / simple (YARN user.name) / basic (SetBasicAuth) - DoWithRedirect: 跨主机跳转保留 Authorization, max 5 默认 - 19 个测试全绿 (httptest 模拟) Phase 4 (admin + audit): - internal/audit: Entry + Repo.Insert/List + MarshalDetails, snake_case JSON - internal/middleware: AdminAuth/AgentAuth (constant-time 比对) - internal/admin: 6 端点 (GET/POST/PUT/DELETE /admin/clusters, GET /admin/audit) + 写操作触发 audit_log (含 before/after diff) + AuthPassword 空=保留旧密码 + 校验: 必填字段 + auth_type 枚举 + rate_limit>=0 - main.go: 挂载 storage.Open + admin.Mount - L fix: audit.Entry 加 json tag (smoke test 发现大写 key 不规范) Co-Authored-By: Claude <noreply@anthropic.com>
