fix(tui): keep configured model and agent when navigating sessions

Navigating between sessions adopted the session's last-used model and agent, which overrode an explicitly configured model/default_agent (or --model/--agent). Skip the auto-adoption when an explicit selection exists so the user's configured choice sticks.
