fix(tui): clear stale scrollback on session switch (#2155)

Browse Source 
fullRender wrote \x1b[3J\x1b[2J\x1b[H (clear scrollback, then clear
screen). But \x1b[2J pushes on-screen content into scrollback, undoing
the preceding \x1b[3J. Reorder to \x1b[2J\x1b[H\x1b[3J so the screen is
cleared first and scrollback is wiped last.
