What this PR does:
The bucket index updater re-read every block's parquet converter marker from object storage on each update cycle, causing a GET call per parquet block per cycle even when nothing changed.
This PR skips re-reading the marker when the block already has a valid-version parquet entry in the previous index, reducing repeated GET calls.
