More E2E tests; export default classes from modules (#8730)

This is a prerequisite for adding a CI action for E2E tests.

- Fix E2E tests
- Remove visual regression testing (VRT) and associated fixtures (screenshots) for now
- Switch dashboard almost fully to Vite, from ESBuild, to match GUI2's build tooling.
- Add some new E2E tests:
- Creating assets
- Deleting assets
- Creating assets from the samples on the home page
- Sort assets
- Includes fixes for sorting:
- Group sorted assets by type again (regression) (see https://github.com/enso-org/cloud-v2/issues/554)
- Make sorting by title, case insensitive. This is because it is more intuitive for non-programmers if all items with uppercase names *aren't* separated from those with lowercase names - especially since the Windows FS is case-insensitive.
- Normalization of Unicode letters is *not* currently being done. It can potentially be added later.
- Double-clicking *anywhere* on a directory row now expands it. Previously it was only being expanded when double clicking
- Add recursive label adding/removal to mirror backend
- Note: The current implementation is not exactly the same as the backend's implementation.
- Fix https://github.com/enso-org/cloud-v2/issues/872
- Unset "saved project details" (for opening the last open project) if fetching it produces an error.

# Important Notes
- All tests pass. (run `npm run test:e2e` in `app/ide-desktop/lib/dashboard`)
- All `npm` commands should be run in `app/ide-desktop/lib/dashboard`. `dashboard:*` npm scripts have been removed from `app/ide-desktop` to prevent a mess.
- `npm run dev` confirmed to still work. Note that it has not been changed as it was already using Vite.
- `npm run build` now uses `vite build`. This has been tested using a local HTTP server that supports `404.html`.
- Other cases have been tested:
- `npm run test:e2e` works (all tests pass)
- `./run ide build` works
- `./run ide watch` works
- `./run ide2 build` works
- `./run gui watch` works
