- 关键词/剧名预检索加 2000 条上限，避免 IN 列表超限并给出可操作提示 - 新增 created_at 分页索引迁移，避免无条件列表退化为全表排序 - dramaPublished 改为三态，短剧已不存在时不再误报未发布

-- K108 后台收藏/点赞列表按时间倒序的分页索引。
|
|
-- 列表默认 ORDER BY created_at DESC, id DESC，且实体走逻辑删除（deleted = 0），
|
|
-- 原有索引只覆盖 (user_id, created_at) / (device_id, created_at) 前缀，
|
|
-- 不加筛选条件时会退化成全表扫描 + 排序。
