### What problem does this PR solve?
Related PRs: #66244, #66263, #66357
Backport the three changes to `branch-4.1` in their master integration
order. Since #66357 has not been merged, this backport uses its current commit
chain as requested.
The backport reduces Paimon JNI allocation overhead, fuses Parquet V2 nested
sparse-selection planning, and keeps safe FileScannerV2 predicate pruning
independent of legacy session gates. It also adapts the FileScannerV2 test
fixture to the `branch-4.1` row-descriptor nullability invariant.
