THEN Fix the query builder's `translateAggregation` function in `web/src/features/query/server/queryBuilder.ts` to avoid wrapping distinct SQL expressions with `count()`. Specifically, change `count(${metric.alias || metric.sql})` to use `metric.sql` directly for metrics like `uniqueUserIds` and `uniqueSessionIds`. Alternatively, upgrade to a version that includes the complete fix (may require patching beyond PR #9808).

// Bug: counts the literal alias instead of distinct values
return `count(${metric.alias || metric.sql})`;
// Fix: for distinct metrics, use the SQL directly:
if (metric.alias === 'uniqueUserIds' || metric.alias === 'uniqueSessionIds') return metric.sql;
return `count(${metric.alias || metric.sql})`;
