Reworked message loading endpoints and services to support flexible message querying with 'before' and 'after' parameters via a new MessageQuery contract. Updated controller actions, service interfaces, and implementations to use the new query model, and improved error handling. Added integration tests for ChatLoadController and introduced IUserPresenceService interface. Minor fixes and help text improvements in console client commands.
Removed Govor.Console implementation and introduced a new Govor.ConsoleClient project with a modular command-based architecture. Added dependency injection, command dispatcher, middleware pipeline, logging, and interactive command support. Updated solution and project files to reflect the new structure.
