Update client.py for new Fern-generated SDK signatures

Remove request_timeout and request_timeout_millis from convenience
methods (query, query_stream, chat, chat_stream, create_chat_session)
and ChatSession class. These parameters are no longer accepted by the
Fern-generated SDK — timeouts are now set via request_options.
