This commit introduces a `ResetModel()` function to `AgentViewModel` and `MineAgentViewModel` to clear their state.
This function is now called in `ResourceCleanupManager` and `AppState` during logout or when switching accounts to ensure that data from the previous session is not retained.
Additionally, the search and group name input fields in `CreateGroupChatScreen` are now single-line.
