Introduced `RemoveEnvelopeReceiverCommand` and its handler to facilitate the removal of envelope receivers. Updated the `EnvelopeReceiverController` to use C# 9's record-like syntax for dependency injection, eliminating explicit private fields. Added a `RemoveAsync` method to handle DELETE requests for removing envelope receivers. Enhanced code documentation with additional XML comments.
