### What problem does this PR solve?
Issue Number: close #65705
Related PR: None
Problem Summary: A MIN_DELTA table stream can expose DELETE events through a
direct SELECT but lose them in INSERT SELECT when the query filters
__DORIS_STREAM_CHANGE_TYPE_COL__. The stream-change column and the raw binlog
operation column share the same physical slot but use different encodings rule.
OlapScanner pushed the output-domain predicate down to storage, where it was
evaluated against raw binlog operation values before BlockReader synthesized
the final stream-change type. This filtered required rows too early. Keep
binlog operation predicates as scanner residuals for MIN_DELTA and DETAIL scans
so they are evaluated after BlockReader produces the stream-change values,
while preserving predicate pushdown for other columns.
### Release note
Fix Table Stream INSERT SELECT failing to emit DELETE events when filtering
by stream change type.
### Check List (For Author)
- Test: No test run (existing regression coverage reproduces the issue)
- Behavior changed: Yes, change-type predicates for MIN_DELTA and DETAIL
scans are evaluated after BlockReader synthesizes the stream-change value
- Does this need documentation: No
