feat(mobile): restore two old-H5 interaction loops in chat form

旧 H5 vs uniapp 逐功能盘点(客户要求'html 版本逻辑保持')后确认的
两个交互缺口,以会话形态补齐:

1. 学练闭环:总结卡底部新增「去练一遍」(旧版'开始跟读'),
   关卡后直达练页预习视图,学完话术立刻练。
2. 建议采用:老师傅提示气泡新增「用这句话回复」(旧版'建议回复'
   的真实数据版),ChatComposer 暴露 setDraft(text)——填入输入框并
   切键盘模式,员工可修改后发送;对打字困难的老年员工是关键路径。

盘点其余结论:旧版功能全部已迁移或被更优实现替代;
团队短板热力图为写死演示数据,真实版记 P2(需后端维度聚合);
演示角色切换/假数据脚手架确认不迁。

验证:本地+生产 E2E——总结卡→去练一遍→预习视图;
对练→老师傅提示→用这句话回复→输入框回填→发送进入下一轮。
发布备份 h5-before-$TS。
