Refactored lazy initialization to use a thread-safe `Lazy<List<TEnum>> _enumOptions` for caching enum options, reducing redundant calls to `GetAllOptions()`. Updated related methods and properties to leverage the cached options. Changed the return type of `GetAllOptions` to `List<TEnum>` for better performance. Simplified the `List` property to directly use the cached options. Introduced a `ConcurrentDictionary` in `TypeExtensions` to cache results of `GetFieldsOfType<TFieldType>`, minimizing reflection overhead. Performed code cleanup, improved formatting, adjusted `using` directives, and ensured thread-safety with `LazyThreadSafetyMode.ExecutionAndPublication`.
