Add VAT rate retrieval logic and enhance test coverage

Introduces a method to fetch the current active VAT rate based on date
and activity status, improving the functionality of VAT rate management.

Enhances test coverage by adding unit tests for the new method and
updating existing tests to ensure robustness. Refines handling of
relation data for better consistency.

Allows configuration to support unsupported PHP versions for
php-cs-fixer, improving compatibility in development environments.
