Implement user session management and JWT refresh tokens

Added user session models, interfaces, repository, and service for managing user sessions and refresh tokens. Refactored authentication flow to return user objects and open sessions with device info, supporting refresh token generation and validation. Updated JWT configuration to separate access and refresh options, and refactored related tests and API contracts. Improved media upload handling and error logging. Migrated dependency references and DI registrations accordingly.
