feat: M-AI-03 Job 查询/取消/Admin/可观测性

- AiJobController: GET /api/ai/jobs/:jobId, POST /cancel（JWT 用户隔离）
  - 公开响应不含 validatedOutput/internalErrorMessage/Snapshot/Credential
  - 终态取消幂等返回
- AiJobAdminController: Admin 列表/详情/重试/队列状态/Outbox 状态
  - 重试：创建新 Job + parentJobId + 复制 Snapshot + OutboxEvent
- AiJobService: 用户/Admin 共享业务逻辑
- WorkerHeartbeat: activeJobCount 改为真实活跃数（ai-interactive + ai-background）
