Improve interactivity by allowing direct bounding box drawing and tool selection

- Updated click_img component to support interactive selection of points and rectangles
- Added tool_select radio button to choose between 'Point' and 'Rectangle' tools
- Modified get_select_coords function to handle rectangle selections
- Updated visualization to correctly display bounding boxes
