refactor: [recent] Refactor recent display widget and session management

Refactored recent display widget to use a unified list view for both projects and documents, improving code organization and reducing duplication.  Major changes include:

- Combined project and document views into single RecentListView
- Improved session management with dirty state tracking
- Refactored session item widget to use animation for expand/collapse
- Updated session service interface for better state handling
- Simplified recent display widget UI layout and event handling
