/**
 * 取消收藏（幂等）
 * DELETE /api/tender/favorites?projectId=123
 * 代理到 mp-api /api/hjc/project-favorite/{projectId}；需登录态。
 *
 * 约定：原样透传 ApiResult{code,message,data}。后端**恒返回 code=0**
 * （本来就没收藏也算成功），结论在 data 里：`{ projectId, favorited: false }`。
 *
 * projectId 走查询串而不是请求体：DELETE 带 body 在部分中间层会被丢掉，
 * 而它本来就是个标识符，放查询串更自然。
