Detailed Description

Add a schema column; undo drops it.

Warning: Undo depends on the GDAL build being able to delete a GeoPackage column (FeatureStore::removeField tests OLCDeleteField). When it cannot, undo leaves the column in place and records the reason in lastError rather than pretending to have removed it.
