### What problem does this PR solve? Arrow Stream Load through the Nereids load planner lowercased source column names even though Arrow schema field names are case-sensitive. For tables with uppercase target columns, the Arrow/Native scan-slot path then resolved the source name through a case-sensitive type map and could fail planning with a null type or construct a scan slot whose name no longer matched the Arrow field. This change preserves source column names for Arrow and Native load formats and resolves scan slot types through the target table's case-insensitive column lookup. -- This is an automated message from the Apache Git Service.
