Subject: [PATCH] fix(home): stop hero channel preview audio when the app is
 backgrounded

Pressing Home while a favorite TV channel previewed in the hero only
stopped the activity; the Home composition stayed alive and its
ExoPlayer kept playing. Gate the hero video on the lifecycle being
STARTED and release the stream on stop so it re-prepares on return.
