This PR adds integrity verification for SSTable component files during loading. When component digests are present in Scylla metadata, the loader now validates each component's CRC32 digest against the stored expected value, catching silent corruption of component files. Index, Rows and Partitions components digests are also validated duriung scrub in validate mode Added corruption tests that write an SSTable, flip a bit in a specific component file, then verify that reloading the SSTable detects the corruption and throws the expected exception. Depends on https://github.com/scylladb/scylladb/pull/28338 Backport is not required, this is new feature Fixes https://github.com/scylladb/scylladb/issues/20103 Closes scylladb/scylladb#28761 * github.com:scylladb/scylladb: test/cqlpy: test --ignore-component-digest-mismatch flag in scylla sstable upgrade docs: document --ignore-component-digest-mismatch flag for scylla sstable upgrade sstables: propagate ignore_component_digest_mismatch config to all load sites sstables: add option to ignore component digest mismatches sstable_compaction_test: Add scrub validate test for corrupted index sstables: add tests for component digest validation on corrupted SSTables sstables: validate index components digests during SSTable scrub in validate mode sstables: verify component digests on SSTable load sstables: add digest_file_random_access_reader for CRC32 digest computation
