Description

Follow-up to feasibility-gui#432.

The frontend currently contains several outdated/unused configuration entries and backend-related settings. These should be centralized and provided by the backend as a config json. The configuration options should be defined as environment variables in the backend’s docker-compose file, read by the backend at startup, and exposed to the frontend through a dedicated config endpoint.

Following options are needed and should potentially be provided
