Build: vendor panel detection dependencies

Update rollup config to copy OpenCV, TensorFlow.js, and COCO-SSD
libraries to vendor directory. These dependencies are used for the
panel detection feature and need to be bundled with the application
instead of loaded from npm packages at runtime.

- Add copyOpenCV() plugin to copy OpenCV.js from node_modules
- Add copyTensorFlow() plugin to copy TensorFlow.js from node_modules
- Add copyCocoSsd() plugin to copy COCO-SSD model from node_modules
- Apply formatting consistency (double quotes for imports)
