feat(duckdb-driver): Fix numeric filter comparisons in DuckDB (#9328)

* feat(duckdb-driver): Fix numeric filter comparisons in DuckDB

Fixes [#9281](#9281) by implementing explicit CAST for numeric filters in the DuckDB driver. This ensures correct numeric comparisons and prevents mismatches caused by string-to-number conversions.

Added test cases to validate casting behavior for different filter scenarios.
