fix：修复 ScriptView 详情面板重复展示及列表预览行数据路径

- ScriptView.openScriptChat 移除重复 push wishTheme/novelContent，改为从 messages 真实数据按 type 映射为 chat-bubble（与 ScriptDetailView.rebuildResultMessages 一致）
- ScriptLibraryView.getOutlinePreview 增加多路径探测（plotJson.stages.outline.beats / fullPayload.outline.beats / plotJson.outline.beats），兼容老剧本数据
