gahusb 4d837fdd31 feat(video-render): worker.py — Redis BLPOP + 4 job_type dispatch (SP-7)
queue:video-render BLPOP, queue:paused 체크 후 dispatch.
string-based _DISPATCH_TABLE + getattr (테스트 patch 호환, Plan-B-Music 패턴).
AttributeError 가드 포함. asyncio.to_thread로 sync provider wrap.
4 job_type: sora/veo/kling/seedance _generation.
Plan-B-Video Phase 2.
