fix(CLI-BH): advance lastTimestamp using max across batch, not just first log

When the newest log in a poll batch lacks timestamp_precise, scanning
only newLogs[0] fails to advance lastTimestamp, causing logs with
timestamp_precise to be re-displayed on subsequent polls. Use a
maxTimestamp() helper that finds the highest value across the entire
batch for both initial fetch and poll updates.
