Description

Part of #599.

Implement append-only INSERT INTO planning for catalog-backed Iceberg tables. Static tables should remain read-only.

Upstream implements TableProvider::insert_into here:

https://github.com/apache/iceberg-rust/blob/f28ae7dca60904a5f135f3b6eecb03b09032b581/crates/integrations/datafusion/src/table/mod.rs#L153-L235

This should only cover append inserts; overwrite and row-level operations are separate work.

Research direction

Start with the upstream TableProvider::insert_into implementation in crates/integrations/datafusion/src/table/mod.rs, lines 153-235, and trace the corresponding catalog-backed Iceberg table provider locally. Implement only append INSERT INTO planning, keeping static tables read-only; verify that overwrite and row-level operations remain out of scope.
