KIMI b95159f7eb 新增 mobile/:畅联手机端 Flutter 工程(B-58)
- 登录:工号+密码走 account-service /api/login,自动登录、被踢下线回登录页
- 消息:会话列表(未读角标/免打扰/时间)、单聊群聊、文字/语音/图片/文件消息、失败重发、历史分页
- 通讯录:新的同事/我的群聊入口、按部门分组(好友 ex 字段)、搜索
- 通话:一对一语音通话(信令走 OpenIM 自定义消息 + LiveKit,token 走 /api/rtc_token)
- 界面按确认效果图 m1/m2/m3 实现,主色 #3B87F5,四态视图齐全,无英文残留
