Taras Veretilnyk 30ff5942c6 database_test: fix race in test_drop_quarantined_sstables ...

The test_drop_quarantined_sstables test could fail due to a race between
compaction and quarantining of SSTables. If compaction selects
an SSTable before it is moved to quarantine, and change_state is called during
compaction, the SSTable may already be removed, resulting in a
std::filesystem_error due to missing files.

This patch resolves the issue by wrapping the quarantine operation inside
run_with_compaction_disabled(). This ensures compaction is paused on the
compaction group view while SSTables are being quarantined, preventing the
race.

Additionally, updates the test to quarantine up to 1/5 SSTables instead
of one randomly and increases the number of sstables genereted to improve
test scenario.
