feat(ducklake): enable compaction by default

Per-flush Parquet files and DuckLake snapshots accumulate quickly; without
periodic merge/expire/cleanup the catalog and file count grow unbounded.
Flip compaction.enable default false -> true so maintenance (including the
inlined-data flush) runs out of the box. Operators can still opt out
explicitly.

Bump 11.0.233 -> 11.0.234.
