feat(emergency): 专家端应急求助入口对齐员工端

- 首页新增员工应急求助入口，接口改用 myParticipatedOrders，1条直接进群聊，多条弹窗选择
- ChatViewController 加急救员流程：isFromFirstAid、群成员面板、工单弹窗
- 急救员入口隐藏语音通话/档案/结束咨询，标题写死"应急求助"
- XJDNetAPI 加 getMyParticipatedOrders/getActualGroupMemberList/getSearchEmployee/getSearchExpert/postAddGroupUser
- 拷贝 XJSelectContactViewController、XJParticipatedOrderModel、checkbox/order 等图标资源
- IM断线静默重登，异地登录弹提示跳登录页
- 首页数量标签默认隐藏，非零才显示
