Introduces a new cryptographic key management system for user sessions, including models, DTOs, interfaces, and services for handling identity keys, signed pre-keys, and one-time pre-keys. Updates the SessionKeysController and DI configuration to use the new services. Adds related EF Core configurations and migrations, and updates the UserSession model to reference the new UserCryptoSession. Removes the obsolete ISessionKeyService interface.
Introduces ICurrentUserSessionService and its implementation to provide access to the current user's session ID via the 'sid' claim. Registers the service in DI and adds comprehensive unit tests to validate correct and error scenarios.
The JwtService now includes sessionId in access tokens, and all usages have been updated to pass sessionId when generating tokens. UserSession now supports public encryption and signing keys. Tests and session management logic have been updated to reflect these changes, ensuring session-specific claims in JWTs and improved session tracking.
Introduces IHubUserAccessor and its implementation to centralize user ID retrieval from SignalR HubCallerContext, replacing duplicated logic in ChatsHub, FriendsHub, and PresenceHub. Moves extension and mapping files to a Common directory, adds UserToUserDtoMappingAction for online status mapping, and implements OnlineUserStore with tests for tracking online users. Updates dependency injection and test code to use the new abstractions.
