feat: implement batch node removal and enhance canvas node management

- Replaced individual node removal with a batch removal mutation to improve performance and user experience.
- Introduced optimistic UI updates to prevent flickering during node deletions.
- Enhanced edge reconnection logic to automatically handle edges associated with deleted nodes.
- Updated asset and image node components to support new metrics tracking for better diagnostics.
- Refactored node resizing logic to ensure consistent behavior during drag-and-drop operations.
