feat(mobile): web-ai chat rebuild (batch 3) + profile page APP-ification

用户三项决定落地:
1. 问AI(全网)页会话化:重写为微信式会话(欢迎/免责=AI气泡,
   脱敏与敏感信息提醒保留,未启用=系统气泡+输入条禁用,
   同意告知由勾选框改为首次发送前确认弹窗(会话内记忆),
   答案气泡带播报+来源N条折叠(外链可点),按住说话松开即发+
   选音频,ChatComposer 复用;无tab栏子页,输入条自带安全区)
2. 配置维持不变(active_timeout/姓名字段/固定验证码按原状)
3. 知识大库开放:财务报备/销售话术/行政制度/培训视频/图片素材
   (1004/1005/1007/1008/1009/1010)绑定移动端应用并授
   employee/supervisor READ;1006「验收测试」为测试库,
   为免污染员工检索结果暂不开放(报告中说明)。
   生产验证:员工问「财务报备流程」「销售话术要点」均返回真实答案。

新需求「H5 像 APP」首批:「我」页 APP 化——折叠不删减:
- 成长摘要保留核心数字,五维评分+成长路径收进「展开能力详情」
- 成长证据包默认收起(标题行+展开按钮)
- 最近练过默认3条,「展开全部N条」可切换
页面高度 3072→1976px,信息全部一次点击可达。

验证:本地5项断言+生产3项复核全过(webai气泡/禁用态/composer、
profile折叠/高度、大库检索)。发布备份 h5-before-20260718092234。
