fix(emergency): 完善应急就医群聊功能—急救员邀请+图标显示+头像兜底

- TUICallingViewManager 启用 initInviteUserFunction，急救员通话中显示右上角 + 号邀请按钮
- InputActionSetting 新增 firstAid 字段，setter 同步写入 SP 供跨模块读取
- createEmergencySetting 支持 firstAid 参数，急救员进入群聊时传入 true
- TUIGroupChatFragment 右侧抽屉图标仅在 firstAid 为 true 时显示
- GlideEngine 新增 loadImageByDefault 兜底加载方法
- GroupMemberAdapter 头像加载使用兜底图标，修复空 URL 显示异常
- GroupMemberAdapter 修复 administrator 群组的成员过滤逻辑
