Having a modest-size files in a project would lead to a timeout when the project was first initialized. This became apparent when testing delivered `.enso-project` files with some data files. After some digging there was a bug in JGit
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=494323) which meant that adding such files was really slow. The implemented fix is not on by default but even with `--renormalization` turned off I did not see improvement.
In the end it didn't make sense to add `data` directory to our version control, or any other files than those in `src` or some meta files in `.enso`. Not including such files eliminates first-use initialization problems.
# Important Notes
To test, pick an existing Enso project with some data files in it (> 100MB) and remove `.enso/.vcs` directory. Previously it would timeout on first try (and work in successive runs). Now it works even on the first try.
The crash:
```

- Implements https://github.com/enso-org/cloud-v2/issues/631
- Tests for dashboard (`app/ide-desktop/lib/dashboard/`):
- End-to-end tests
- Unit tests
- Component tests
The purpose of this PR is to introduce the testing framework - more tests can be added later in separate PRs.
# Important Notes
To test, run `npm run test` in `app/ide-desktop`, or `app/ide-desktop/lib/dashboard/`. All tests should pass.
Individual test types can be run using `npm run test-unit`, `npm run test-component` and `npm run test-e2e` in `app/ide-desktop/lib/dashboard/`.
Individual end-to-end tests can be run using `npx playwright test -c playwright-e2e.config.ts test-e2e/<file name>.spec.ts` in `app/ide-desktop/lib/dashboard/`.
End-to-end tests require internet access to pass (for things like fonts).
