Implement fullscreen preview functionality and optimize storage URL handling

- Added fullscreen output capability for render nodes, allowing users to view images in a larger format.
- Introduced a dialog component for fullscreen image display, including a close button.
- Enhanced storage URL resolution with performance logging to identify slow queries and improve efficiency.
- Updated various queries and handlers to include performance metrics for better monitoring and debugging.
