Subject: [PATCH] fix(chat): collapse trust/rating strips while the keyboard is
 open

On short screens (e.g. landscape) the fixed-height trust and rating
strips plus the composer overflowed the body once the keyboard shrank
it. Wrap the two secondary strips in HideWhenKeyboardOpen so they yield
their vertical space while typing and reappear when the keyboard closes.
