…window filteringRefactors the time-based filtering in ClickHouse inference stats queries:- Changed time_window_to_ms to time_window_to_duration returning std::time::Duration- Use ClickHouse's UUIDv7ToDateTime function for timestamp comparison instead of  manual bit manipulation of UUIDv7 format- Pass time delta in seconds to ClickHouse, use INTERVAL SECOND for arithmetic- Preserves original semantics of filtering relative to max timestamp in the dataFix inference stats e2e test assertions- Check RFC 3339 format with milliseconds on raw HTTP response body instead of  re-serializing DateTime (chrono's default serializer omits .000 for zero ms)- Relax variant count assertion from 2+ to 1+ for fixture data flexibility
