Convert `<group-list-item-out-of-scope>` to React

 - Extract an SVG element in order to give it a name and clarify what it
   is for
 - Improve a link `title`
 - Remove an unnecessary extra space

Add ESLint plugin to check React hooks usage

Usage of "hooks" has to follow certain rules [1]. This adds the official
ESLint plugin to check for this.

All the checks are marked as errors following the "no warnings, only
errors" principle. ESLint suppressions can be used to ignore any cases
where we decide not to follow a "rule".

Enable async-await support

Replace a usage of AngularJS promises ($q)

The tests have been modified to work in terms of the UI instead of
internal controller methods, since there is no controller instance any
more.

Support creating UI components with React

Respond to CR feedback.

Add a factory which takes a React/Preact component and returns an AngularJS
component that wraps it.

The wrapper handles rendering of the component and injecting Angular
services that the component needs as props.

 - Add Preact dependency
 - Enable use of JSX in the linter and during transpilation, configured
   to work with Preact.
 - Enable the ESLint React plugin, configured to work with Preact.

Enable conditional inclusion of code based on NODE_ENV checks

Refactor new groups menu
