Removed unnecessary parameters from CreateEnvelopeReceiverCommand, simplifying envelope creation. Updated EnvelopeReceiverController to reflect these changes by removing related fields from the JSON response, focusing on essential information.
Removed `CreateEnvelopeCommand` and introduced `CreateEnvelopeReceiverCommand` with updated parameters. Updated `ReceiverGetOrCreateDto` to include a new `Salution` parameter. Added XML documentation for the new command and associated DTOs.
