### What problem does this PR solve?
Issue Number: DORIS-28201
Problem Summary:
`INSERT INTO` a file TVF used output names as map keys while binding the
query output. When multiple expressions shared the same alias, the later
expression replaced the earlier one, so the later value was written more than
once.
This change keeps file TVF outputs in query position order. It also adds an
analyzer unit test and a local file TVF regression test for duplicate output
names.
### Release note
Fix duplicate output aliases writing the wrong positional values to file
TVFs.
