Review Comment:
Fixed in 4af3a54491. Schema-fallback child projections now copy
timestamp_is_adjusted_to_utc from the history-annotated file schema, including
filter-only nested children.
FilterOnlyNestedTimestampRetainsTableFormatSemantic pins the unannotated INT96
TIMESTAMP_LTZ(9) mapper path, and paimon_timestamp_types now projects one
struct child while filtering on its LTZ sibling.
