feat: Update environment configurations and enhance SQL handling with new validation tests

- Refactor environment files to include a new debug configuration.
- Change log level in the main config to DEBUG for better traceability.
- Modify SQL queries to use `literal_column("*")` for selecting all columns.
- Introduce validation tests to ensure correct handling of NULL values and spec overrides.
