fix(serialization): Remove legacy BinaryFormatter support

The `[Serializable]` attribute and corresponding `[OnDeserialized]` methods have been removed from various breakdown classes. This eliminates reliance on `BinaryFormatter`, which is a deprecated and insecure serialization mechanism in modern .NET.

This change also resolves SonarQube rule S5766 warnings by removing the context in which they apply, leading to cleaner and more secure code.
