Fix word wrap in RichLog panels

Set min_width=0 on RichLog widgets so text wraps at actual panel width
instead of the default 78 characters. With 3 side-by-side panels, the
default caused text to render wider than the panel and get clipped.

Also adds text-wrap: wrap CSS property for completeness.
