feat(gpu): #1978 AI数字人口型同步接入MuseTalk GPU Worker

业务侧（LipsyncService）集成 GpuLipsyncService：
- 新增开关 USE_GPU_LIPSYNC（env，默认false；staging默认true方便联调，生产默认false待稳定后开）
- _submit_audio_direct 在签名提交 MediaKit 前判断：
  * 开关关闭 → 直接走现有 MediaKit 云端 lipsync
  * 开关开但无可用 Worker（last_heartbeat_at 超5分钟窗口） → 回退 MediaKit
  * 开关开+Worker可用 → 创建GPU任务→同步轮询等待结果
- GPU路径成功：直接标记 job.status=completed、output_video_url=签名后的结果URL
- GPU超时（默认1200s）/终态failed/异常 → 全部回退 MediaKit，对用户透明
- 轮询间隔默认5s，可配 GPU_LIPSYNC_POLL_INTERVAL
- Worker心跳新鲜度窗口可配 GPU_WORKER_STALE_SECONDS（默认300s）

GpuLipsyncService新增方法：
- has_available_worker()：判断5分钟内有心跳的Worker存在
- wait_for_result(task_id, timeout, poll_interval)：同步轮询DB等待终态，
  期间顺手 _recover_timed_out_tasks；超时返回None让调用方兜底

env/CI配置：
- .env.example 新增4个配置项注释
- deploy/configs/.env.staging USE_GPU_LIPSYNC=true（联调）
- deploy/configs/.env.production USE_GPU_LIPSYNC=false（暂不开）

单元测试：tests/unit/test_lipsync_gpu_integration.py 9个用例覆盖：
- 开关关不调用GPU、无Worker回退、GPU成功completed、超时回退、
  failed回退、异常回退、has_available_worker三种场景
- 全部 30个GPU相关测试全绿（含此前11+10个）
