Fixes#11604
Most issues were caused by a problem with Project List flooding the network with its requests - this was fixed on develop.
But one assertion was flaky - it assumed we will see the "real" run result on `write` node, but sometimes it is immediately overwritten by dry run.
But the most important part of this PR is adding traces to Electron packages - it's should be much easier now to debug E2E test failures.
Also renamed the previously misnamed "E2E tests" to "[GUI] integration tests".
Fixes#10668Fixes#8484
Summary of changes:
* `gui2` and `dashboard` are merged to `gui` directory. Various configs were merged (package.json, playwrigth, TS...). The src and e2e directories are split to `dashboard` and `project-view` for now.
* E2E tests run two servers on different ports. The tests are organized in projects. This is also to be changed soon, as we plan to [use better mocking in GUI/ProjectView](#9726)
* ESlint configs were merged to central `eslint.config.mjs`, and that file was moved to repository root. We kept the dashboard lints, but they can be relaxed. The dashboard code was changed to meet GUI lints.
* Also, the versions of linter plugins were bumped, and code fixed.
* The ide-desktop/client no longer has `dashboard` dependency - the only type used there was moved to common package.
* `common` package moved to `app`.
