Enhanced the auto.offset.reset documentation in ConsumerConfig.java to
clearly explain the message-loss risk when using latest after increasing
the partition count, and recommended by_duration: as a safer
alternative.

Updated basic-kafka-operations.md with a recommendation section and a
comparison table for suitable <duration> values under both the
consumer (KIP-848) and classic group protocols.
