refactor: Add use_rollup parameter to base summary builder

Add explicit use_rollup parameter to BaseSummaryBuilder that can override
the automatic rollup detection logic. This allows the comparison rake task
to explicitly control whether to use rollup or raw data without toggling
feature flags. Cleaner approach that avoids database writes during comparison.
