URL: https://github.com/apache/paimon/pull/9925
### Purpose
When a data evolution scan applies row ranges to a `QueryAuthSplit`,
`wrapToIndexSplits` casts the authorization wrapper to `DataSplit` and fails
with `ClassCastException`.
Convert the wrapped split to `IndexedSplit` and retain the outer
`QueryAuthSplit` and its authorization result, so row filters and column
masking remain available to the reader. Reuse existing indexed splits without
changing their row ranges or scores.
### Tests
Added regression coverage for authorization results (including null),
intersected row ranges, scores, and existing indexed splits. The new
authorization test reproduces the `ClassCastException` before the fix.
All 15 tests passed with the standard build checks enabled:
```sh
mvn -pl paimon-core -am -DfailIfNoTests=false -DwildcardSuites=none \
-Dtest=DataEvolutionBatchScanTest,QueryAuthSplitTest,SplitSerializerTest
test
```
