* Multiple UI errors in [#453](https://gitlab.phaidra.org/fair-data-austria-db-repository/fda-services/-/issues/453).

The infrastructure now checks in the backend if the services are ready. Mostly this is done through creating a file upon Spring Boot @PostConstruct, for the metadata db it is done with PostgreSQL pg_isready
