dennis zhuang ef1298ce02 fix(query): accept narrowed nullability in MergeScan remote schema check (#9592 )

On append-mode tables a region reports an exact row count. When it is
zero, DataFusion's AggregateStatistics replaces the region-side
__min_state/__max_state aggregate with a non-null struct literal, so the
remote stream advertises the state column as non-nullable. The MergeScan
schema check required equal nullability and failed the query.

Accept a remote field that is non-nullable where the expected field is
nullable, matching DataFusion's own physical-plan schema invariant.
Batches are already rebuilt with the expected schema. Widening is still
rejected, and nested field nullability is still compared exactly as part
of the data type.
