feat(desktop&tenant): Enhance desktop account and task consumer presence management

- Added new fields to DesktopAccountInfo for tracking account session and task consumer online status, along with queued publish task count and oldest queued publish task timestamp.
- Updated DesktopDispatchEvent to include server time for better synchronization.
- Implemented separate presence management for task consumers, including marking presence and loading presence state.
- Enhanced DesktopAccountService to apply publish queue summaries and manage task consumer presence.
- Introduced new methods for replaying queued publish tasks in DesktopDispatchHandler.
- Updated tests to cover new presence management logic and ensure correct behavior of account session and task consumer online status.
