fix(jetbrains): keep the account overlay hidden after a prompted worktree start

Creating a worktree with a prompt opens the new session and dispatches the prompt in the same EDT event, so the history load resolves afterwards with no messages and fired ViewChanged.ShowEmpty. That re-showed the account overlay and wedged the view state, because showSession() early-returns once model.showSession is set, so hideAccountOverlay() could never run again and the account chip stayed on top of a running session. setControllerViewState now ignores ShowEmpty once the transcript is shown.
