COOPS-UI: should use a-la-carte Vuetify components to reduce app load size

## Description:
The coops-ui vendors chunk size is excessive (4.2 MB) as seen in the dist/js folder after `npm run build` (or in dev tools network tab). More detail can be seen by loading the Webpack Bundle Analyzer Plugin:

```
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

module.exports = {
configureWebpack: {
plugins: [
new BundleAnalyzerPlugin()
],
devtool: 'cheap-module-eval-source-map'
},
...
};
```


One (relatively) easy gain would be to use so-called a-la-carte Vuetify components (aka tree-shaking to determine only those components needed). Ref: https://vuetifyjs.com/en/customization/a-la-carte

I tried to get this working quickly but was unable... hence this ticket.
