CVE-2026-33142: OneUptime ClickHouse vulnerable to SQL Injection via unvalidated column identifiers in sort, select, and groupBy parameters

The fix for GHSA-p5g2-jm85-8g35 (ClickHouse SQL injection via aggregate query parameters) added column name validation to the _aggregateBy method but did not apply the same validation to three other query construction paths in StatementGenerator. The toSortStatement, toSelectStatement, and toGroupByStatement methods accept user-controlled object keys from API request bodies and interpolate them as ClickHouse Identifier parameters without verifying they correspond to actual model columns.

ClickHouse Identifier parameters are substituted directly into queries without escaping, so an attacker who can reach any analytics list or aggregate endpoint can inject arbitrary SQL through crafted sort, select, or groupBy keys.
