* 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 commit updates the OpenDC web server to make use of Quarkus Quinoa
for serving the web UI. This allows us to deprecate the complex Quarkus
extension for serving the web UI.

ensure we follow Quarkus Quinoa's conventions.

This change updates the OpenDC web UI to not rely on Sass for
stylesheets. CSS in combination with PostCSS has become powerful enough
for our use-cases as indicated by the small differences between the CSS
and SCSS versions of our files.

By switching to CSS, we can make use of Turbopack to build the project,
which is a re-implementation of Webppack in Rust and is able to build
projects much faster.

This change reduces the height of the application header to 3.5rem to
increase the screen real-estate that we can use for the application
content.

This change moves the project selector into the masthead since it
affects the whole application. This follows the PatternFly guidelines.

This change addresses an issue with the context selector component where
the dropdown would fall behind a sticky tab bar in the main content.

This change updates the dependencies of the Next.js-based web UI to
their latest available versions where possible.

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 adds context selectors for the OpenDC frontend where the
user can select different projects, portfolios or topologies from the
context selection bar.
