closes #3644
Log tables with a declared bucket key weren't hashing appends by it and every row in a flush landed in one bucket (sticky), unlike the KV/upsert path and the Java client, so bucket-key co-location was silently broken.
Now the append path hashes by the bucket key like Java:
append(row)hashes each row, andappend_arrow_batchsplits a batch across buckets (single-bucket batches send as-is, mixed batches fan out per bucket).Tables without a bucket key are unchanged.
