fix(media): 修复emby电影库混入剧集/特别篇识别/剧集合集 + 新增手动编辑元数据

emby 兼容层(hills/yamby 等客户端):
- 电影库不再混入剧集:filterLikelyEpisodicPathsFromMovieQuery 按路径
  特征(Season/S0x/Specials/电视剧/日番/国漫等)剔除误入电影库的剧集
- itemPayload 改用 mediaShouldBeEpisode:有季集号且(属剧集库或路径像剧集)
  才标记为 Episode,修正电影库里剧集被当成 Movie

特别篇识别:
- episode_parser 新增 patSpecialSeason,识别 S0/Season 0/Specials/SP/OVA/
  OAD/番外/特别篇/特典 文件夹 → 第0季;seasonFromParents 返回 found 标志,
  区分"明确第0季"与"未识别默认第1季"
- emby seasonDir 正则同步支持 Specials/SP/OVA/特别篇 等

剧集合集:
- groupSeries 抽出 isSeriesCard,卡片链接按是否剧集判定,修复剧集卡片
  跳转;每集分离的根因(季集号/分组key)随入库识别修复一并改善

手动编辑元数据(自采集视频无TMDB信息时可自定义封面/标题/简介/分类):
- 新增 MediaService.UpdateMetadata + PATCH /media/:id/metadata(需admin)
- 前端 MetadataEditDialog 接入 LibraryPage 与 MediaDetailPage

其他:scanner/scraper/nfo/local+cloud_metadata/adult 元数据识别配套改进;
.gitignore 忽略本地 .dev-cache/.dev-data 运行产物。
