Add _set_timestamp_defaults event listener to populate created_at/updated_at
before insert when using SQLite, since func.now() server_default is stripped.
Extended server_default stripping to include "now()" expressions for
timestamp columns (created_at, updated_at) that were failing with
NOT NULL constraint errors.
Fixes remaining CI test failures after PR #35:
- NOT NULL constraint failed: stores.created_at
- NOT NULL constraint failed: normalized_products.created_at
