feat(#2039): viral video domain + repository + REST API + Celery orchestrator（PR2/2）

- domain: ViralVideoJob 状态机（PENDING/RUNNING/WAIT_USER_CONFIRM/COMPLETED/FAILED/CANCELLED）、
  11 阶段枚举、PromptType 7 值（含 v1.3 video_style_integration/style_constraint）
- repository: 接口 + SQLAlchemy 实现（jobs/style_templates/prompt_templates）
- API: 6 个 REST 端点（generate/history/detail/retry/confirm-intent/analyze-style/style-templates）
- Celery: ViralVideoOrchestrator 10 步流水线，WS viral_video:progress 进度推送，
  Credits CREDITS_VIRAL_VIDEO_COST=50 扣点/失败自动回滚
- ai_service: 新增 call_llm/call_vision（复用现有豆包客户端）
- 测试 40 个单测（domain/schema/repository/流水线/集成）
