fix: implement node highlighting feature in Canvas component

- Added a timer to highlight located nodes for a specified duration.
- Introduced CSS styles for visual feedback on locating nodes.
- Updated the dataflow store to manage the located node state.
- Enhanced the locateNode function to reset the highlight after the duration.
- Adjusted related components to reflect the new highlighting state.
