HDDS-13499. Intermittent failure in OM DB Size Reduction After Compaction

[sarvekshayr]

What changes were proposed in this pull request?

The intermittent failure was caused by sst files not being generated immediately after creating a large number of keys.

This is resolved by restarting the OM container after key creation, which forces a flush and triggers sst file generation. Additionally, reduced the number of keys to be created, as the OM restart ensures sst files are created even with fewer keys.

Thanks for the quick fix @sarvekshayr! The changes are looking good to me, do you think we should do fork runs for this suite (like at #8771)? How often did it occurred on the master CI?
