### What problem does this PR solve? Issue Number: [DORIS-27025](http://39.106.86.136:8090/browse/DORIS-27025) Related PR: #65502 Problem Summary: Iceberg partition evolution may classify a column as an identity partition column because of a newer partition spec, while files written by an older spec (for example, `bucket(3, int_col)`) still store that column physically. Pruning the reader schema to query slots can therefore make matching rows from older ORC files disappear when a predicate references the evolved column. #65502 already made Iceberg scans send the complete schema for equality-delete dependencies. This PR records that the same invariant is required for partition evolution and adds a focused FE unit test proving that a non-projected evolved partition column remains in the reader schema. ### Release note None ### Check List (For Author) - Test - [ ] Regression test - [x] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
