feat(frontend): 专项调研页适配 v2 契约 - 按 code 拉取问卷 + 提交选项 id (survey-rework)

- survey.vue：loadQuestions 改调 getProblemSurveyQuestions(code)，后端未绑定模板时返回内置默认问卷（不再依赖 getActiveTemplates 匹配）；toggleOpt 按选项 id 选择；submit 统一 [{questionId, optionIds}]
- flow-intro.vue：surveyTemplateId 取值修正（后端返回平铺字段，兼容嵌套 surveyTemplate.id）
- api.js：新增 getProblemSurveyQuestions(code)
