This is done by making it possible to render the GenericError, Layout
and Footer with a `dontSuspend` prop. This then sets the `useSuspense`
to `false` in translations, and sets a default translations in case they
haven't been loaded yet.
* Start replacing jotai with @tanstack/router
* Remove jotai completely
* Move the common layout & reimplement the ?action parameter
This also makes sure everything is properly loaded in the route loader,
and we use fragment where it makes sense
* Change the default error component
* GraphQL API: make the sessions fetchable through node(id: ID!)
