Subject: [PATCH] Clear the terminal buffer when the viewport is resized.

Growing the terminal exposes cells that ratatui never repaints, because the
frame-wide Clear in draw() only covers the area it currently believes is the
viewport. Wipe the whole buffer on Event::Resize so the next frame starts
clean instead of painting around leftover text.
