merge: Migrate to Quarkus-based web API

This pull request changes the web API to a Quarkus-based version. Currently, the OpenDC web API is written in Python (using Flask). Although Python is a powerful language to develop web services, having another language next to Kotlin/Java and JavaScript introduces some challenges.

For instance, the web API and UI lack integration with our Gradle-based build pipeline and require additional steps from the developer to start working with. Furthermore, deploying OpenDC requires having Python installed in addition to the JVM. 

By converting the web API into a Quarkus application, we can enjoy further integration with our Gradle-based build pipeline and simplify the development/deployment process of OpenDC, by requiring only the JVM and Node to work with OpenDC.

## Implementation Notes :hammer_and_pick:

* Move build dependencies into version catalog
* Design unified communication protocol
* Add Quarkus API implementation
* Add new web client implementation
* Update runner to use new web client
* Fix compatibility with React.js UI
* Remove Python build steps from CI pipeline
* Update Docker deployment for new web API
* Remove obsolete database configuration

## External Dependencies :four_leaf_clover:

* Quarkus

## Breaking API Changes :warning:

* The new web API only supports SQL-based databases for storing user-data, as opposed to MongoDB currently. We intend to use H2 for development and Postgres for production.
