Re: [PR] Spark: Add regression test for MERGE struct nullification [iceberg]

   @pvary Could you take a look? This adds regression tests for #16246 (MERGE silently nullifies non-nullable struct children). Tests cover multi-row MERGE (matched + unmatched rows), NULL parent struct preservation, and verify assertions are meaningful against the fixed code. Thanks!
