EnvelopeDto now implements the IEnvelope interface, enabling it to be used wherever IEnvelope is required. No other modifications were made to the class.
The ReadOnly property logic was shifted from the Envelope entity
to the EnvelopeDto record, ensuring that read-only status is
determined at the DTO layer rather than in the data model.
- Add logic to skip access-code workflow if UseAccessCode is false
- Auto-authenticate receiver and show envelope immediately
- Preserve rejection and signed checks
- Keep existing behavior for access-code enabled envelopes
