Subject: [PATCH] Preserve import error tables during freeze

- Remove 'import_polygon_%' from UPDATE_TABLES to keep import_polygon_error
and import_polygon_delete tables in frozen databases.

- These tables contain permanent import error tracking data and should not
be deleted during freeze. The ro-access grant system expects them to exist
in all database states.
