fix: deconstructPoints 接口拿不到解构数据

根因:
1. result_json 字段是 BLOB 类型,需用 selectByExampleWithBLOBs 才能加载,
   原代码用 selectByExample 拿不到这个字段,所以 rawResult 永远 null
2. 即使本地 result_json 为空,正确做法是调 videoSearchService.getDeconstructResult
   (内部会用 taskId 调外部 API + 回填本地表),原代码无此 fallback

修复:
- 改用 selectByExampleWithBLOBs 加载 result_json BLOB 字段
- 本地无 result_json 时, 包装 GetDeconstructParam 调
  videoSearchService.getDeconstructResult(taskId) 拿真实数据 + 回填
- 透传 result 字段(含 point_label/inspiration/purpose/keypoint 等真实层级)

实测 channelContentId=8075198879 现在能拿到完整解构 JSON,
含 关键点 / 灵感点 / 目的点 三级结构,前端 DeconstructTree
递归渲染即可,无需改前端。
