### What problem does this PR solve?
Problem Summary:
Problem Summary: TopN lazy materialization resolved deferred column indexes
with output slot names. Queries that renamed Hive columns therefore produced -1
indexes, and external row-id fetch could fill those columns with NULL when
positional reading was used. Resolve the index from the already traced original
base column so the descriptor and index share one column identity. Add a
focused planner unit test and a Hive ORC Explain regression for the alias path.
Fix incorrect NULL values from aliased external-table columns when TopN lazy
materialization is used.
