+收藏和点赞分页参数：`pageIndex` 默认 1，`pageSize` 默认 10、最大 100；
+`keyword` 模糊匹配 uid/昵称，`userId`、`deviceId`、`dramaId` 精确匹配，
+`dramaTitle` 模糊匹配；`startTime/endTime` 按创建时间闭区间过滤，
+格式 `yyyy-MM-dd HH:mm:ss`。点赞另支持 `targetType`（DRAMA/EPISODE/COMMENT）、
+`targetId` 和 `episodeId` 精确过滤，短剧和剧集过滤会解析评论及剧集所属关系。
+按 `createdAt DESC, id DESC` 排序，用户/短剧预检索无结果返回 total=0、list=[]。
+
+收藏行字段：`id,userId,uid,nickname,deviceId,anonymous,dramaId,dramaTitle,dramaCover,
+dramaStatus,dramaPublished,createdAt`。点赞行字段：`id,userId,uid,nickname,deviceId,
+anonymous,targetType,targetId,dramaId,dramaTitle,dramaCover,episodeId,episodeNo,episodeTitle,
+commentSummary,createdAt`。游客的 userId 为空、anonymous 为 true；评论摘要最多 30 字。
+关联资料逻辑删除后展示字段为空，不排除原始互动记录。
