Add agent selection and artifact management to RowboatX UI

- Implemented agent selection dropdown in the input area.
- Enhanced artifact management with loading, saving, and error handling.
- Added new API routes for fetching agent summaries and run details.
- Updated sidebar to display agents, configurations, and runs dynamically.
- Introduced theme selection options in the user navigation menu.
