Refactor ReCClient.Static to Create() method

Replaced the `ReCClient.Static` property with a `ReCClient.Create()` method to improve clarity and align with best practices. The new method retains the same functionality, including throwing an `InvalidOperationException` if the `Provider` is not built. The logic for retrieving the `IHttpClientFactory` and creating a `ReCClient` instance remains unchanged.
