### Purpose
<!-- Linking this pull request to the issue -->
`IN` min/max pruning is opt-in in the shared statistics evaluator. Parquet
page statistics enabled it in #704, but Parquet and Mosaic row-group statistics
still used the default fail-open behavior. As a result, non-matching row groups
could not be skipped, including in Parquet files without page indexes.
<!-- What is the purpose of the change -->
### Brief change log
<!-- Please describe the changes made in this pull request and explain how
they address the issue -->
- Enable min/max pruning for `IN` predicates using Parquet and Mosaic
row-group statistics.
- Preserve fail-open behavior for missing, inverted, or incompatible
statistics.
- Add regression tests for row-group selection and avoided Mosaic column
reads.
