Preserve chat when returning to Home; add Clear chat control

Stop resetting chat history from applyHomeState() so sidebar Home and
re-selecting Home no longer wipe the thread. Add a Clear chat button
above the transcript that calls resetChatState(); disable it while a
search request is in flight to avoid races with late completions.
