fix: adjust method formatting and add dynamic attribute access

Corrected indentation for method definitions to align with coding standards. Introduced a `__getattr__` method for dynamic attribute access, improving flexibility when interacting with the `calls` attribute. This ensures better error handling and forwards attribute requests to the first call in the list when applicable.
