Subject: [PATCH] fix: use theme background when ShowMore gradient color is
 transparent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Several callers pass Color.Transparent as the rich-text backgroundColor.
getGradient was copying that color and forcing alpha=1, which produced
opaque black (Color(0,0,0,1)) as the gradient end — so on a light theme
the fade behind the "Show more" button looked pitch black.

Fall back to MaterialTheme.colorScheme.background when the supplied
background has alpha 0, so the gradient fades from transparent into the
actual surface color.
