feat(organize): 整理时指定季集结构(临时剧集组 / 同时设为作品结构)

- 契约:FilesOrganizeRequest.episodeStructures(按作品 groupId / applyToEntity),组响应带 episodeStructure
- 集数映射:createStructureEpisodeMapper 按指定结构的季表(剧集组带原季集对照)换算;作品规则先按作品结构命中,再经 TMDB 原季集换到指定结构
- 资产覆盖:指定结构季集 → TMDB 原季集 → 作品当前结构的单元,换不回不登记集覆盖;冻结计划记 episodeStructure 与 facts.structureEpisodes
- 向导执行勾选「同时设为作品的季集结构」时先走 setEpisodeGroup 切换作品再整理
- 测试:organize-episode-structure(SPLIT_COUR_FIXTURE)
