Use Quarkus Quinoa for serving web UI (#391)

* 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.

* refactor(web): Migrate to Quarkus Quinoa

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.

* refactor(web): Move web UI into Quarkus web app

This commit moves the web UI into the Quarkus web server module to
ensure we follow Quarkus Quinoa's conventions.

* refactor(web): Merge Quarkus extension into single module

This commit merges the existing Quarkus extensions into a single module
to prevent build complexity.

* refactor(web): Migrate web proto to Java

This commit migrates the web protocol to Java and removes the dependency
on Jandex Gradle.

* 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.

* enable DB schema migration on DEV server

* webui is not needed anymore

* remove MAINTAINERS is depricated

* fix quarkus.quinoa properties

* revert properties change, install npm in docker image to allow building the frontend

* pin postgres version, this is a best practice. Fix some properties the old ones are depricated. Added properties for local testing

* fix build error

* :opendc-web:opendc-web-proto:spotlessApply

* fix database schema
