feat(api): 专项调研重设计 v2 - 统一问卷契约 + 内置默认问卷 (survey-rework)

- 新增 POST /api/problem-survey/questions：按问题域 code 返回问卷（未绑定模板时返回内置默认问卷，选项带 id/tag 供 resultTags 聚合）
- submit 改读 surveyTemplateId（兼容旧 templateId），answers 统一 [{questionId, optionIds}]（兼容旧 Map/[{questionText, optionTexts}]）
- ProblemDomainController.list 补平铺 surveyTemplateId 字段（修复 flow-intro 透传断链）
- 迁移248：survey_templates 内置 3 个问题域问卷种子（空表才插入）+ problem_domains 未绑定才绑定，幂等
