docs: apply eng review findings to design doc and impl plan
Architecture fixes:
- Image QA: presigned URL → base64 (RustFS is internal, GLM-4V is cloud)
- Add GET /health endpoint + Docker healthcheck
- Video size limit: add get_object_size() to StorageClient ABC, check before background task
- Video size configurable via MAX_VIDEO_SIZE_MB env var (no image rebuild needed)
- Fix image_service.py except clause redundancy (Exception absorbs KeyError/TypeError)
Config additions:
- video.max_file_size_mb: 200 in config.yaml
- MAX_VIDEO_SIZE_MB env override in _ENV_OVERRIDES
