Merge pull request 'fix(vision): image_analysis prompt XML/JSON冲突修复 + v4 JSON prompt seed' (#2216) from feature/vision-v4-prompt-fix into develop

- _prompt: DB有active image_analysis prompt时原样使用，不再追加硬编码schema，
  让DB prompt完全控制输出格式（修复DB写XML、调用强制json_object导致解析失败、
  商品图全部走fallback的问题）
- assembler: 新增v4嵌套schema路由（product/store/person/other四类），
  保留旧扁平schema兼容，下游零改动
- vlm_fallback: pro兜底结果统一走assembler.assemble_result，与fast路径输出一致
- migration 097: 固化staging已验证的v4 JSON prompt并置为active（幂等）
