Pass the real table schema into KeyValueTableRead in test helpers so keyValueSequenceNumberEnabled() can read schema options without NPE. Co-authored-by: Cursor <cursoragent@cursor.com>

Only emit delete-only compact commits at job end, use restore-only state for dynamic-bucket sort compact, and compact test data before checking raw-convertible splits. Co-authored-by: Cursor <cursoragent@cursor.com>

Purpose
Follow up on #7595 per this review comment: sort compact should not be modeled as an OVERWRITE commit with extra base-snapshot handling. Instead, it should produce a normal COMPACT commit so the existing commit protocol can perform compact validation and conflict detection.
This PR fixes the concurrent-write data loss risk in sort compact by refactoring Flink/Spark sort compact to:
No new overwritePartition(baseSnapshotId) APIs or special overwrite conflict logic are introduced.
