refactor(query): restructure ReceiverAlreadySignedQuery for clarity

- Replaced internal string properties with EnvelopeQuery and ReceiverQuery records
- Updated Key property to encode/decode using the new structured types
- Added overloaded IMediator extension methods IsSignedAsync for better usability
- Simplified ReceiverAlreadySignedQueryHandler to work with the new structure
