Add DocResult property and update EnvelopeController

- Introduced a new `DocResult` property in `EnvelopeDto.cs` and `Envelope.cs` for handling binary data.
- Rearranged properties in `EnvelopeDto.cs` for better organization.
- Modified `EnvelopeController` to return a collection of envelopes instead of a single envelope.
