主要结果： PPT： 已完成步骤可自由返回，刷新后保留当前步骤。 结果页改为固定三栏视口，缩略图和质量面板独立滚动。 修复画布宽度计算和宽高自适应缩放。 返回配置页时恢复上次模板。 Worker 禁止静默替换模板，不兼容时明确失败。 结果页显示实际应用的模板。 海报解析与合规： 修复 insured/policy 嵌套字段映射。 增加 partial/failed 解析质量判断和缺失字段提示。 传入险种、产品、保司和别名上下文。 修复性别、币种归一化和错误字段计数。 新增服务端字符级合规接口与生成前复检。 不合规文字可高亮、点击定位并选中对应文字。 海报编辑： AI 图片现在作为背景资产，不再替换整个海报。 单图、长图生成后仍可编辑标题、正文、CTA、数据和卖点。 背景生成失败不会清空当前编辑内容。 下载时合成背景、文字、数据、图表和免责声明。 增加可编辑文档快照、最终 PNG 保存和历史继续编辑。 新增数据库迁移：[migrate_028.py](/D:/work/code/python/coding/baodanagent/api/insurance/db/migrate_028.py) 验证结果： 专项及相关后端测试：26 passed, 1 skipped Python 全模块编译检查：通过 前端生产构建：通过 git diff --check：通过 全量测试收集受本机缺少 python-pptx 依赖影响，报错为 ModuleNotFoundError: pptx，不是本次修改产生的测试失败。
