* refactor(web): Migrate to Quarkus 3

This commit updates the OpenDC web server to use Quarkus 3, which
changes annotations to use the Jakarta namespace for annotations.

* refactor(web): Configure runtime variables for web UI

This commit updates the web UI to propagate runtime variables via the
next-runtime-env package. Before, we would need to replace the variables
in the generated sources by Next.js, next-runtime-env works by loading a
JavaScript file when opening the OpenDC web UI which contains the
configuration of the web app.

This change fixes #135 which showed that trying to delete a topology
used by a scenario would result in nothing happening in the UI and a 500
error being returned by the server. We check whether a scenario still
references the topology and show an error to the user if that happens.

Fixes #135

This change updates the OpenDC web UI to show the monthly simulation
budget of the user in the user dropdown. This provides the user with a
progress bar of the used simulation minutes.

This change updates the web UI and API to support unauthenticated user
access. Such functionality is helpful when there is just a single user
that wants to try OpenDC.

This change updates the web interface in React to be compatible with the
new API written in Kotlin. Several changes have been made in the new API
to ensure consistency.

This change updates the source structure of the OpenDC frontend to
follow the page structure.

This change updates the OpenDC frontend to combine the fetching of
project relations. This means that for a single project, we make only
one additional request to retrieve all its topologies.

This change updates the OpenDC frontend to fetch schedulers and traces
using React Query, removing its dependency on Redux.
