test(desktop): 修复 Trump IM 集成后 13 个测试——IMView/IMContactList/IMMessageInput/useIMChat

IMView: 更新 mock 适配新 hook API（friendRequest/notification/actionState）
IMContactList: 替换 add-contact 测试为 hubContacts/onAddContact API
IMMessageInput: 适配 Trump 发送后文本保留行为
useIMChat: sendMessage 改用 Hub REST client 而非 WS

26→16 失败，其中 15 个是预存（edge-real）或用户新测试。
