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`.
Resolves#9607 by computing `Number.hash` by converting given number to `Float` first and then computing the hash. Also the conversion from `Float.to Decimal` is exact - done via `new BigDecimal(double)`. There is `Decimal.new` that handles the user-friendly conversion. However as a result `Decimal.from 2.1 != Decimal.new 2.1` - that's the only way to ensure consistency between hash code and conversions.
This PR adds support for the new Vue-based GUI (aka `gui2`).
The user-facing changes are primarily:
* support for `./run gui2` and `./run ide2` commands (that build just the new GUI and the whole IDE package with new GUI embedded — respectively);
* the top-level `test` and `lint` commands will now invoke the relevant commands on the new GUI
