fix: 修复集成测试中发现的全部 bug — 15 服务端到端验证通过

修复涵盖 6 大类问题： 1. api-gateway - 路径前缀剥离 /api 而非 /api/v1，保留下游 /v1/ controller 前缀 - JWKS URL 默认值修复 - publicPaths 白名单对齐 /v1/iam/* 2. iam - iam.module.ts exports 补充 PermissionCacheService 和 IamRepository - main.ts resolveProtoPath() 多路径探测 proto 文件 3. core-edu - app.module.ts AuthMiddleware 全局注册 4. BFF 层 GraphQL 端点（teacher-bff / parent-bff / student-bff） - teacher-bff: mock dataScope OWN→SELF 对齐 GraphQL enum；WHATWG Request header .get() 提取 - parent-bff: handleNodeRequestAndResponse 不存在 → 直接 yoga(req,res)；WHATWG Request header .get() 提取 - student-bff: auth.resolver 移除 ActionState 信封返回扁平对象；WHATWG Request header .get() 提取 5. ai - Kafka 事务降级 + 10s 超时 - gRPC 拦截器降级 - dev mode 禁用事务模式 6. 前端 + 共享包 - teacher-portal: MF 插件条件实例化 + transpilePackages + extensionAlias - ui-components: error-boundary.tsx 添加 use client - ui-tokens: tailwind-theme.css 移除 @layer base - shared-ts: 导出从源码改为 dist 编译产物；OutboxModule global:true 7. infra - .gitignore 补充 keys/ *.pem *.key secrets/ 排除规则 - infra/init-sql/02-all-services-schema.sql 36 张表 DDL 验证结果： - TS typecheck: 19 个 workspace 项目全部通过 - Go vet + Ruff: 通过 - 15 服务全部启动成功 - 3 个 BFF GraphQL 端点 + 4 个前端页面全部 200 - Gateway → iam → core-edu 端到端链路验证通过 AI identity: trae-main（集成测试修复会话）
