### What problem does this PR solve?
Issue Number: close #65339
Related PR:
Problem Summary: Queries that place `LogicalOlapTableStreamScan` under a CTE
can skip stream normalization in the old rewrite placement, so the stream
virtual columns are still treated as scan outputs when later rules derive
operative columns. That leaves hidden stream columns unresolved in the delta
refresh path and can fail IVM incremental refresh planning. This PR carries two
FE fixes into master: preserve `LogicalOlapTableStreamScan` during deep
copy/CTE rewrite, and run `NormalizeOlapTableStreamScan` in the CTE children
rewrite pipeline after partition pruning but before `OperativeColumnDerive`, so
CTE and non-CTE paths both lower stream virtual columns into project aliases
consistently.
### Release note
None
### Check List (For Author)
- Test: Manual test / No need to test (with reason)
- No additional test included in this master-only backport branch
- Behavior changed: Yes (CTE stream-scan planning now normalizes in the
correct rewrite phase)
- Does this need documentation: No
