### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
`LogicalCTEAnchor` previously implemented `PropagateFuncDeps`. Since it is a
binary plan node, the default implementation merged data traits from both the
CTE producer and the right child.
However, a logical CTE anchor exposes only the output of its right child.
Merging the producer's data traits could therefore introduce traits associated
with slots that are not part of the anchor output, leading to incorrect logical
properties.
This change makes `LogicalCTEAnchor` propagate data traits exclusively from
its right child. It also enables and extends the CTE unit test to keep the CTE
anchor from being inlined and verify the propagated traits.
