feat(editor): update editor limits and add error boundary

- Reduced maximum document size for the editor from 5MB to 1MB.
- Introduced a new line limit of 5000 for documents in the editor.
- Implemented a PlateErrorBoundary component to handle rendering errors gracefully in the editor panel.
- Updated logic in the editor panel to check both size and line count for document limits.
