feat(aihr): switch interview and case flows to real-model-first pipeline

AI 面试 /start 动态出题、/finish 按真实回答结构化评分(未配模型用本地
Rubric 估分);案例沉淀 /upload 改 multipart 真实语音+ASR 转写,
/organize 用真实 transcript 调 chat 模型整理;seed service 重构为
AihrInterviewService/AihrCaseService;前端面试/案例/对练页与移动端、
demo-check、验收文档同步真实链路口径。
