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:
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.
