Preserve target extension metadata in INSERT

[osipovartem]

Summary

• enforce target Arrow field metadata after INSERT storage-type coercion
• preserve extension markers when source and target share the same storage type
• cover INSERT SELECT and parameterized UUID-extension plans

Why

DataFusion compared only storage DataType while aligning INSERT columns. That drops target extension metadata such as arrow.uuid; Rustice needs the same field-level guarantee for native logical timestamp types.

Validation

• 586/586 datafusion-sql integration tests passed
• cargo clippy -p datafusion-sql --all-targets --all-features -- -D warnings
• cargo fmt --all -- --check
