feat(helm): add KRO context tags to default resource tags

Add managed-by and kro-version tags to the default helm template configuration. These tags help identify KRO-managed resources in AWS CloudTrail logs, cost allocation reports, and usage metrics. Tags with empty values are automatically skipped to keep resources clean.
