### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: Add coverage for Iceberg/Paimon deletion-vector split and
cache scenarios. The Iceberg regression writes one data file with one deletion
vector, forces tiny splits, validates the filtered result with qt_, and checks
the profile reports a single materialized deletion vector across multiple
scanner entries. Paimon split/cache queries are converted to qt_ checks with
generated expected output. Existing BE cache-key tests include scenario
comments for Iceberg, Paimon, and format_v2 Paimon paths.
