compaction/scrub: register sstables for compaction before validation When `scrub --validate` runs, it collects all candidate sstables at the start and validates them one by one in separate compaction tasks. However, scrub in validate mode does not register these sstables for compaction, which allows regular compaction to pick them up and potentially compact them away before validation begins. This leads to scrub failures because the sstables can no longer be found. This patch fixes the issue by first disabling compaction, collecting the sstables, and then registering them for compaction before starting validation. This ensures that the enqueued sstables remain available for the entire duration of the scrub validation task. Fixes #23363 This reported scrub failure occurs on all versions that have the checksum/digest validation feature for uncompressed sstables. So, backport it to older versions. - (cherry picked from commit84f2e99c05) - (cherry picked from commit7cdda510ee) Parent PR: #26034 Closes scylladb/scylladb#26097 * github.com:scylladb/scylladb: compaction/scrub: register sstables for compaction before validation compaction/scrub: handle exceptions when moving invalid sstables to quarantine
