v.25.12Bug Fix (user-visible misbehavior in an official stable release)

Close https://github.com/clickhouse/clickhouse/issues/87417 the writing schema of v1

Close https://github.com/clickhouse/clickhouse/issues/87417 the writing schema of v1 format has a mistake : the type of "added_snapshot_id" should be "long" rather than "null, long" because it is required. it is a bug because it's not compatible with other system like spark. when we mixed there manifest files, the bug happens. #92078 (Han Fei).
