Enhance LoadingPlaceholder and Object Components with Lazy Loading Support

- Updated LoadingPlaceholder to accept new props for border and height customization, improving flexibility in loading states.
- Integrated lazy loading functionality across ObjectCard, ObjectKanban, ObjectKanbanColumn, ObjectKanbanHeader, and ObjectTable components, enhancing user experience during data fetching.
- Adjusted rendering logic in ObjectTable to display LoadingPlaceholder when data is being fetched, providing clearer visual feedback to users.
- Refactored prop types in relevant components to include lazy loading options, ensuring consistent API across components.
