fix: use wechat-oa login, username unfriendly

[xhyqaq]

背景

在使用公众号登录后用户显示昵称为wxuser + xxxxxxxx，对于用户体验极不友好，因此需要修改昵称

方案

• 用户首次使用公众号登录后，弹框显示 "请修改用户昵称等信息" -> 友好提示用户修改昵称
• 用户首次使用公众号登录后，强制修改用户昵称为自定义名称
• casdoor方面提pr，可自定义用户昵称算法

方案流程 1.需要在表中添加字段用于记录弹框标记，避免后续再次弹框 2.用户无感知，较友好 3.casdoor方面需要在公众号页面预留添加用户昵称算法拓展点

采取方案 2

该方案实现简单，动用代码少，且能尽快实现

测试

• 使用公众号登录后查看用户信息昵称是否发生改变
