#### Context:
Offline mode is one of the core features of the dashboard. Unfortunately, after adding new features and a few refactoring, we lost the ability to work offline.
This PR should bring this functionality back, with a few key differences:
1. We require users to sign in before using the dashboard even in local mode.
2. Once a user is logged in, we allow him to work with local files
3. If a user closes the dashboard, and then open it, he can continue using it in offline mode
#### This Change:
What does this change do in the larger context? Specific details to highlight for review:
1. Reimplements `<AuthProvider />` functionality, now it implemented on top of `<Suspense />` and ReactQuery
2. Reimplements Backend module flow, now remote backend is always created, You no longer need to check if the RemoteBackend is present
3. Introduces new `<Suspense />` component, which is aware of offline status
4. Introduce new offline-related hooks
5. Add a banner to the form if it's unable to submit it offline
6. Refactor `InviteUserDialog` to the new `<Form />` component
7. Fixes redirect bug when the app doesn't redirect a user to the dashboard after logging in
8. Fixes strange behavior when `/users/me` could stuck into infinite refetch
9. Redesign the Cloud table for offline mode.
10. Adds blocking UI dialog when a user clicks "log out" button
#### Test Plan:
This PR requires thorough QA on the login flow across the browser and IDE. All redirect logic must stay unchanged.

* kill the electron process instead of restarting
limit the port range with single one
Make ENSO_CLOUD_REDIRECT optional, use window.location.origin by default
* Revert server changes
* limit the amount of ports in server
- Close https://github.com/enso-org/cloud-v2/issues/866
- Remove *all* references to client keys and API base URLs from the codebase.
- The app can still be built by external contributors. *However*, the cloud backend (among some other things) will be completely disabled, as the required keys and base URLs will be missing.
- Add entry to `.gitignore` to allow `*.env` files in `app/ide-desktop/lib/dashboard/`
# Important Notes
- Tested (no `.env`; `.env` with prod backend; `.pbuchu.env`) on:
- `npm run dev` in `app/ide-desktop/lib/dashboard/`
- `./run ide build`
- `./run ide2 build`
- `./run gui watch`
