fix: re-detect databases at execution time for cluster cleanup

- Detection in preview may fail or return stale results
- Re-detect user databases when cleanup is enabled at execution time
- Fall back to preview list if re-detection fails
- Ensures actual databases are dropped, not just what was detected earlier
