Rename an owned chat session

PATCH 
/api/v2/chat-sessions/:session_id

Updates only the title. Leading and trailing whitespace is removed. A changed title increments the session revision and updates updated_at; repeating the current title leaves the revision unchanged. Turns and messages are preserved.
