Refactor message loading API and add message query support

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.
