Subject: [PATCH] Refactor return value in EnvelopeReceiverController

Modified the method to return a single item or null by using
`SingleOrDefault()` on the result of `await _mediator.Send(...)`.
This ensures the response is no longer a collection but a single
object, improving clarity and aligning with expected behavior.
