### Apache Iceberg version None ### Query engine None ### Please describe the bug 🐞 The initialDefault value in case of a Struct column is always null, but its fields can have default value, The Iceberg layer allows to set & store initialDefault values for the primitive fields of a Struct type. But doesn't honor them while reading. For Paquet: https://github.com/apache/iceberg/blob/c02d4676f38b834d6c672bb53abd34b07ebfddb9/parquet/src/main/java/org/apache/iceberg/data/parquet/BaseParquetReaders.java#L289-L292 This code block checks whether the initialDefault is not null, for Struct type it will always be `null` but its fields can have default values. It should check for the nested fields in case of struct or not allow having initialDefault values for sub fields of Struct type: A same screenshot: <img width="2056" height="1430" alt="Image" src="https://github.com/user-attachments/assets/c0b2fcba-9ced-484a-b47c-34270d3d9833"; /> The field Initial Default is `null` but the nested fields like `x` have an initial default of `100`, but this gets ignored ### Willingness to contribute - [ ] I can contribute a fix for this bug independently - [ ] I would be willing to contribute a fix for this bug with guidance from the Iceberg community - [ ] I cannot contribute a fix for this bug at this time -- This is an automated message from the Apache Git Service.
