Updated PHPStan, refactor getter syntax for consistency and clarity

Updated multiple getter methods to use explicit `get` blocks for improved readability and maintainability. This change ensures a uniform style across all getters, reducing ambiguity and potential future errors. Additionally, upgraded PHPStan to version 2.1.0 in the composer.lock file.
